1. The discharge in the siphon is 2.80 cfs, D = 10 in., L1 = 3 ft, and L2 = 3 ft. Determine
the head loss between the reservoir surface and point C. Determine the pressure at
point B if three-quarters of the head loss (as found above) occurs between the
reservoir surface and point B.

discharge of 10 m3/s is to flow through this
horizontal pipe, which is 1 m in diameter. If the
head loss is given as 7V2/2g (V is velocity in the
pipe), how much power will have to be supplied to
the flow by the pump to produce this discharge?
