Water flows through a cast iron pipe with a diameter of 30 mm. The pipe is inclined at an angle of 3 degrees from horizontal and is 40 m long. The water flows due to gravity only. What is the maximum volume flow rate of the water?

You may ignore any minor loses.

Solutions

Expert Solution

length L = 40 m

diameter D = 30 mm = 0.03 m

acceleration due to gravity g = 9.81 m/s2

head = h

head loss = hL

Maximum volume flow rate of water (Discharge)= Q

Maximum volume flow rate considering major loss(frictional loss ) = 0.000812 m3/s

Maximum volume flow rate neglecting all loses both major and minor losses = 0.00452 m3/s
