Dear

Parshall:

January 11, 1926

Vfe very carefully went over .your letter of fTanuary 6t:Q.

and blue print which was enclosed showing the proposed pipe line to re~lace the old wood flume. in the College Farm Tiitch near Avon, Colo.

The first thought that occurs to us is why you wish to

. use a full round pipe supported on grade its entire length; the alter-nate installation which we have in mind being a semi-circular metal· flume at an appreciably lower cost, for the structure to support the pipe will also support the flume and as shown by quotations given be-low the flume is much lower in cost per foot, oan be transported much more easily to the installation site and installed for a lower labor

cost, however, we do not wish to discourage the recommended install- .

ation for the use of full round pipe as an inverted syphon. We merely . suggest the alternate type of structure for your consideration.

of the same size and gauge plus 50%. We might explain, that the labor charge is the addition-al cost for cutting and welding the elbow and does not include any length of pipe and to fig-ure a total price, the price per foot will ap-ply for the entire length of pipe line as

measured on center line of the pipe from inlet to outlet. To this total will be added two 2 piece elbows and one 3 piece elbow.

1 You will note that we have quoted on 18 and 20 inch dia-meter pipe and also on two sizes of flume, all of which is in addition to that on which you requested prices. In checking the carrying capa-city of the 21 n pipe, we find that a 20n double riveted pipe will del-iver 5 cubic feet per second on the slope indicated and due to the

smooth interior of the automatic electric arc welded pipe an 18" welded pipe will deliver 5 cubic feet per second on the slope indicated. Dif-ference in the carrying capacity between the riveted and smooth

inter-4

ior welded pipe is illustrated by the table on riveted pipe given on pages 176-7 and of the welded pipe on page 178 of our Catalog

il2, a copy of which you have. The increased carrying capacity and

resultant l Jwer friction factor is due to the elimination of all

laps in the metal both 1n the longitudinal and circumferential seams

and elimination of the rivet heads.

In case semi-circular metal flume is used, #42 will

deliver 5 cubic feet per second on the slope indicated as shown by

discharge chart on page 48. You will note that #42 flume .will

del-iver this ~uantity with a freeboard of 1/10. the diameter or

approx-imately 2-3/4n. You may prefer to provide additional freeboard in which case we would recommend #48 with a freeboard of four to five incheso

In the suggested type of supporting structure for the pipe, we believe you wish to place the bents at such distance to

en-able the pipe to be self-supporting, in which case the number of

bents that can be eliminated by using longitudinal stringers'tosupport

the flume on 16 to 20 ft spans as described on page 37, will more than

pay for the longitudinal stringers. It may be there are conditions

which do not make it advisable to install the pipe as an inverted syphon laying it on a shelf on the hillside.

Our quotations on the pipe do not include rods for bolting the pipe to the bents. No size of caps being shown, we are not sure just what length of rod will be required, although, we will gladly furnish quotations on these rods complete with rolled threads and nuts for each end, the rods being either black or galvanized as desired.

. The writer is interested to know whether it is your

intention to be in Denver during Stock Show leek and if so, we would

more than welcome the opportunity of show·ing you our method of

man-ufacturing the automatic electric arc welded pipe, its strength and

any other information which you would be interested to obtain. It is

rather hard to convey this informatio~ by letter and we sincerely

hope the opportunity will present itself in the near future to fam-iliarize you with its constructiono

In checking over our file copy of your

letter of the 11th, we note the prices for ti42 .ARMCO

Ingot Iron and Steel flume were transposed. v· e are

not sure that the original copy sent to you was corrected,

although, it seems to us that it was and that we merely overlooked changing our file copy.

In the event we did not change your copy

this will serve as a correction. The price for the !42

20 gauge Galvanized ARMCO Ingot Iron Flume should be

$

.96-t

and the same made of Galvanized Steel
