The Board of Regents met in the Office of President Clark at
7 o'clock Wednesday evening, July 30th.  Present:  Chairman
Pratt, Mrs. Hood, Judge Talbot, Vice President Adams and Comp-
troller Gorman of the University, and Mr. Duncan, Junior member
of the firm of Coddington and Duncan, who put in the central
heating plant in 1908.

Mr. Duncan had been asked to come to Reno to make a survey of
the heating system.  His oral report was purely a preliminary
report, since he had not finished his checking and had made no
studied analysis of his findings.  However, he stated the heat-
ing problem could be met in either one of 3 ways:

    1.  Perfection of the present plant
    2.  Changing from hot water to steam
    3.  Segregation of units
        a.  Central to take care of academic units
        b.  Dormitories
        c.  Outlying buildings used for only portion of
            University year

Whatever it is decided to do, Mr. Duncan advised that nothing
be thrown away that could be used.  A lot of the pipe is very
good, as he found by examination of at least 8 points in the
manholes and in the buildings.  The pipe seems to be in very
good shape except perhaps in one or two remote places where
oxidation has taken place.

It is quite possible with a hot water system properly designed
to heat buildings a mile away.  The present plant was designed
several years ago to take care of the Gymnasium, Lincoln and
Manzanita Halls, Chemistry building, Hatch Station, Stewart Hall,
President's House, Mechanical building and the Mackay School of
Mines.  The proposition was balanced and worked well.  Attaching
new buildings not at that time planned for had thrown the system
out of balance.  Approximately 2/3 of the radiation on the Campus
is located in the two new units and those two buildings have
robbed the others.  If radiation from hot water is to be used,
the temperature of the water must be 180 degrees.  Lincoln and
Manzanita are receiving water at a temperature of 120 degrees,
or 2/3 of what should be the heat.  It is quite possible to make
those buildings heat provided the distributing mains are made to
suit.

The heating of the training quarters presents a distinctly
separate problem, since it is not used more than 3 months con-
secutively.  It might be wise to keep this building on the
central heating plant, but valve it 500 feet this side of the
building.  It is valved at present at the building.

For the hot water distribution, I think you can add to your
present system and still make it work.  It will mean changing
certain mains and increasing the boiler capacity.  With any one
of the 3 systems, I would still believe from my knowledge of the
conditions now that it would be a very wise move to keep the
central plant for reasons of economy and the Mechanical building
as the logical point.  The operating expense is considerably
less where the heating is all cared for by one central plant.

Mr. Duncan was of opinion that unless this Board of Regents dif-
fered greatly from humankind in general, if "temporary" heating
arrangements were made for the Dormitories and the Dining Hall,
which were satisfactory, the temporary arrangements would be
continued until they became permanent.

If change is made to steam, the problem is entirely one of wheth-
er the pipe size would be the correct size to feed the different
buildings.  For hot water system the pipe sizes are judged in
this manner:  Radiators closest to point of application of heat
have connections very much smaller than those at the farthest
end of the run.  The radiator for the Mechanical building immedi-
ately over the boiler would require 1/4" pipe while radiators at
Lincoln Hall would require 1 1/2" pipe for the simple reason that
the radiation at more remote points is not so great.  With steam
the same size of pipe is used for same size radiator because
steam is of one volume.  In very long runs, pipe sizes are in-
creased perhaps one size, from 1 1/4" to 1 1/2".  For steam
system vacuum pumps are required.  Heat can be furnished much
more quickly with a vacuum system which circulates steam into
buildings so that they are warm in an hour and a half whereas
it requires two or three more hours to heat a building with hot
water system.  Change in pipe sizes would have to be made in
changing from hot water to steam, change would have to be made
on all radiators, return elbow on the opposite side would have
to be taken off and vacuum installed.  I think all radiators can
be very easily changed over by installation of steam valve and
vacuum pipe.  With the present hot water system there is an 8"
flow main which separates into two 5" mains.  With steam the
main pipe would need to be 10" with two 8" mains.  However, the
8" main may be very satisfactory.  There are now two 3" mains
to Lincoln Hall which might have to be replaced by a 4" distrib-
uting pipe and a 1 1/2" vacuum return.  However, the 3" pipes
may be satisfactory.  I cannot tell until I have checked the
load.  Larger pipes are required to carry steam than water if
low pressure steam is used.  If you use high pressure steam with
reducing valve in every building you have a constant source of
maintenance, almost as great as though there were a boiler in
each building.

I believe your present boilers are overloaded.

Comptroller Gorman inquired if Mr. Duncan had considered at all
the use of the Dairy building as the future site of the central
heating plant.  Mr. Duncan had and suggested that eventually the
heating plant should be located in the Dairy building, that pro-
vision should be made for expansion, that the central heating
plant should be made one of the show places of the Campus; that
the change should be done well, if at all.

Mr. Duncan stated that it would take him a month to make a de-
tailed report so that the contractor could bid intelligently and
that the contractor would need at least two weeks to prepare the
bids.  This would leave but two weeks before the first of Octo-
ber, at which time the Regents felt that heat must be available.
The necessary work involved by a change to steam, or of putting
the hot water system in balance could not possibly be accomplish-
ed in that time.  The calculations involved in a hot water system
are about 10 times as great as in steam system.  Only two plans
are feasible for this year; either continuation of hot water
distributing system or temporary plants in outlying buildings;
that is, using present plant and forcing circulation of water to
remote buildings by installation of pump or installing boilers
in outlying buildings.  The hot water system is the only system
where continuous heat is required for 24 hours for a period of
a month or more.

The University has paid for radiators in Agricultural and Educa-
tion buildings 3 times larger than are needed because the heat-
ing plans for these 2 buildings were made by the architect and
not by a heating engineer.  The architect's only concern was that
the buildings should be heated, so the owner suffers by paying
for larger pipe sizes, more radiation, overheating buildings
and the robbing of outlying buildings.  The cost of the surplus
radiation would have paid 3 or 4 times over for engineering
services.  When you build new buildings, let the people who laid
out your system put it in balance for you.

In a steam system the return pipe should be half as large as the
distributing pipe and a vacuum pump is required.  The pipe rises
at this Institution are all exposed so the change to steam could
readily be made.

The Agricultural and Education buildings are receiving 11,600
square feet of radiation as against 19,200 square feet on the
Campus, or 11/19 of the entire load.

Mr. Duncan said air silk cover is the poorest kind of insulation
and that 85% magnesia covering should be used.  All basement
pipes should be covered to conserve heat since radiators furnish
sufficient heat for basements.

Mr. Duncan asked the Board for definite instructions as to what
they desired him to cover in his report so that he might waste
no time in elaboration of some phase of the system in which they
were not interested.  The Board instructed him to make complete
report on both temporary and permanent propositions.

Mr. Duncan then withdrew.

Vice President Adams suggested that the Board might like to pass
a motion before the opening of the University's first semester
on the automobile nuisance on the Campus.  After a general dis-
cussion Judge Talbot moved that automobiles, motorcycles and
other vehicles be denied the right to come on the University
grounds during the hours 7 A.M. to 5 P.M. all days except Satur-
day afternoons and Sundays and University holidays during the
University year, except mail, express and delivery cars and such
persons as have special permits; that all automobiles appearing
on the Campus do so at their own risk; and that gates be install-
ed at all entrances to the University Campus.  Vote:

    Mrs. Hood            Aye
    Judge Talbot         Aye
    Mr. Pratt            Aye

Regent Pratt then opened the bids for fuel oil, which were as
follows:
