4. The discharge pipe of a pump is 400 mm in diameter delivers
0.5 m3/sec of water to a building which maintains a pressure of
100 Kpa at a height of 30 m, what power must be furnished by the
pump?
A pump at an elevation of 300m is pumping 0.05 m³/s of water through 2.4 km of 150-mm
pipe to a reservoir whose level is at an elevation of 380m. What pressure will be found in
the pipe at a point where the elevation is 335m above the datum and the distance
(measured along the pipe) from the pipe is 970m? Compute the capacity of the pump. Use
E/D= 1.5384x10-³
The reservoir tank shown contains fresh water air pressurized to 200 kPa. There is a loss of 3.3
N*m/N due to friction in the pipes. Point 1 is located at the surface of the water and point 2 is in the
free stream of the exit spray. The Distance from the water surface to the free stream is 3 meters.
The flowrate for the system is .05 m^3/s (Work on paper required)
