What is Head Loss

22 · Water at 20°C is pumped through a smooth cm-diameter pipe 10 km long, at a flow rate of 75 m 3 /h.The inlet is fed by a pump at an absolute pressure of 2.4 MPa. The exit is at standard atmospheric pressure (101 kPa) and is 200 m higher.. Calculate the frictional head loss H f, and compare it to the velocity head of the flow v 2 /(2g).. Solution:

Let's calculate what will happen to the pressure if we flush a toilet while a shower is running in a bathroom 100 feet away from where the water enters the house. We are using 1/2 inch pipe. Toilet flow = 2.5 GPM Shower Flow = 2.5 GPM Total flow = 5 GPM. Constant from table multiplied by 0.4335 = Pressure loss in PSI. 39.2 X .4335 = 16.99 PSI.
