Q = quantity of water in cubic feet per minute.
W = weight of water in pounds. H ^effective horse-power.
Example: what horse-power is obtainable from an undershot wheel, with about 35 per cent efficiency, using 1500 cubic feet per minute, with a head of 2 feet? Answer: H=. 00066X1500X2=1. 98 H. P. , or Q = s ~ =1496 cubic feet per minute.
Breast Wheels. The following calculations will ex- plain how to arrive at the effective horse-power of breast whe...els: Low breast wheels : H =. 00104 Q X h.
