At the given flow rate of Q = 1 m^3s^-1 the pressure drop in this pipe is found to be 98 kPa/100 m. The pipe is 720 m long. What is the gauge pressure at the pump outlet (in kPa)? Do not enter the units in the answer box.

Solution

pipe length is= 720 m

pressure drop in the pipe= 98 kpa/100 m

the pressure drop in the pipe= (98/100) * 720 =705.6 kpa

velocity is same at the inlet and out let of pipe, so kinetic diatum loss is 0

diatum head change is 0 at 1 and 2

so the gauge pressure at the pipe inlet is 705.6 kpa
