The Virginia enterprise. [volume] (Virginia, St. Louis County, Minn.) 1893-19??, 1910-12-09

Estimate on wiring to lights and motors
cannot estimate as do not know how
much of this is now done.
Exhaust from engines would all be used
for heating except such days in fall and
spring when outside temperature is high
enough to require no artificial heat in
buildings In cold weather you would not
get enough exhaust for heating unless
Your engines were both running and carry
ing full load, which probably would never
occur. so YOU would have to add live steam
to make up the deficiency.
The available heat in exhaust steam can
best be illustrated as follows: If 100000
British Terminal units of heat goes to an
engine in given time-saY one hour
there being less than so less of heat in
passing through engine would leave $4,000
British Terminal Units available for heat
ing out of the 100000 British Terminal
Units that were delivered to engine. That
Is. $3.50 of the coal burned would be used
for heating and $50 Should be charged to
the engine for power.
Estimate $4,000 for coal to one engine.
$50 of $8O0.OO... ...... . .........$ 40 90
Engine Observation-Disclosures. 100 90
Extra help........ luUU W
Actual cost for power for one year $1140 90
Your committee informs us that in the
new building you have 80 III. P. in motors
and the best rate obtainable was SC per K.
w. hour. with $500 minimum H. P. per
month. If the minimum is applied it
would be $4,000 per month - $4,000 per
year for power alone at new building. If
You have 20 H. p. at the Roosevelt at same
rates add $4890O and if equivalent to so H.
P. for lights in both buildings were used
| at same rate add $4,000 per month $4,000
per year. This would indicate minimum
charge per year for current, $3S40O0 Should
you use enough current so the minimum
would not be applied, so much the worse
for You. Therefore let US use the mini
mum. $3.50 90
Cost to operate generators ......... 114O 90
Net saving on current.......... :. $500 90
This would pay go interest on ...... $4,000
or 1919 on 80. ........ :. 1900
or N9o on.....-... ............ lOUU
Should the cost of plant exceed the
estimate of $780, 90 by $4,000 and make the
plant cost 100000 even, the plant would
earn 296 on the investment and would
therefore pay for itself in three years and
nine months
~
that you now have purchased be exchang-
ed for direct current motors and direct cur
rent generators installed, if satisfactory
change can be made with the companies
furnishing the motors. If such satisfactory
arrangements could not be made we can.
however, install the low voltage general
ors, which would do the work but not so
satisfactorily as the direct current.
Here we leave you to draw your own con-
clutions, and YOU are at liberty to make
any changes in the figures that may ap-
pear to you necessary. Am of the opinion
that no matter how you Jungle them there
is enough to go on to still make a good
showing in favor of plant.
Yours truly,
L. A. LARSON
Moved by J. H. Fleming seconded by r.
J. McGhee, that the Board of Education of
Independent School District of Virginia
enter into contract with r. B. Whitacre
& Co. of St. Peul. for two high speed, self
oiling. automatic, Chuse engines, and two
Is K. w. Spraeue Generators as per spec
ifcations in the hands of the Board for
$7759.00 and that the Virginia Plumbing &
Heating Co. be allowed 1212R twelve and
one half per cent? of the total cost of the
plant for installing the same according to
plans and specifications furnished by L.
A. Larson.
Carried unanimously
On motion duly seconded and carried a
committee consisting of n. A. Holmer, J.
H. Fleming and Lafayette Bliss, was NAM
ed to arrange for the exchange of motors
now in the Virginia High School building.
and to execute formal contracts between
the parties named in the above motion
and the Board. The com mittee was given
power to act in the matters named and
was directed to meet at ten o'clock the fol-
lowing day to close up the business.
