Session 10, Handout 10M

A community of 100 people requires 20/gal/day/person, and 30 gpd/cow for 35 cows, and wants to use a concrete hydram.

h = 90'

H= 20'

A weir 2" wide and 4" deep has been put in the stream; 2' upstream from the weir, the distance form the mark on the stake, level with the top of the weir, to the water level is 1½" Assume an efficiency of 50%, determine the following:

• Q

• D

• d

• Accumulator diameter

• L

• Check valve opening

• Impulse valve opening

• T. s

• TL

• Impulse valve thickness

• Impulse valve seat width

• Impulse valve backing thickness

• Check valve seat width

• Check valve backing thickness

• Number and size of bolts
