Two pipes A and B, each of § cm diameter branch off from a point 1 in a pipe line and rejoin at 2. Pipe A is 500 m and pipe B is 2000 m long. The total head at 1 is 25 m. A short pipe of 10 cm diameter is fitted at B and flow is discharged into atmosphere through it. If F is 0.02 for all the pipes, discharge in pipe B will be.

A cylindrical tank of water is 20 m in diameter and 3.5 m tall. There is a 1.0 cm diameter hole at the bottom from which water is leaking. A feeder pipe at the top of the tank, 4.0 m above the ground delivers water at a rate of 0.02 m/min. Ir the tank is initially half full, tal what is the water flow rate in m^3/sec from the top feeder pipe? (bi what is the pressure at the bottom of the tank? (Hint: Bernoul's principle) () what is the water speed at the bottom? (d) what is the leaking flow rate at the bottom? fe) at what rate is the volume of water changing? (Assume the tank is open to air at the top)

The total discharge in the system below is 15.5 cfs and the head loss from B to C is 24 ft. Using n = 0.011 for all pipes, determine the following: a. head loss hl1 (ft) in pipe 1, and b. head loss his (ft) in pipe 5. 2000 ft 12 in 3000 ft 1500 ft 4000 ft 30 in 10 in 24 in А В D 2500 ft 4 15 in
