Attachment 16-D

Session 16, Handout 16D

Problem 16A:

How much water can be pumped to a delivery head of 200 feet, when there is a drive head of 2 feet, a supply of 50 gpm, and an assumed efficiency of 50%?

Problem 16B:

A community of 200 people, with 70 cows, needs 5 gpd per person and 15 gpd per cow. A spring flows at a rate of 15 gpm, H = 10', h = 100', n = 50%, L:D = 960. How can the community's needs be met?

Problem 16C:

How much water can be delivered to a supply tank 50 feet above a hydram when the drive head is 5 feet, the hydrams efficiency is 50%, the flow rate of the water is 30 gpm, and the largest drive pipe available is 2"?
