1.A 48-in water main carries 79 cfs and branches into two pipes at point A. The branching pipes are 36 and 20 in. in diameter and 2800 and 5000 ft long, respectively. These pipes rejoin at point B and again form a single 48-in. pipe. If the friction factor is 0.022 for the 36-in. pipe and 0.024 for teh 20-in. pipe, what will the discharge be in each branch?

2.Water is pumped from a reservoir whose surface elevation is 1390 ft to a second reservoir whose surface elevation is 1475 ft. The connecting pipeline is 4500 ft long and 12 in. in diameter. If the pressure during pumping is 80 psi at a point midway on the pipe at elevation 1320 ft, find the rate of flow and the power exerted by the pumps. Also, plot the hydraulic grade line. Assume that f = 0.022.
