Water is flowing at a rate of 0.07 m3/s in a frictionless supply system that includes a pump that has a power of 897 W. The system is not open to the atmosphere. What is the manometer reading (in m)?

Solution

From the formula

power = unit weight * Q*h

897=10000*0.07*h

h=897/(1000*0.07)

=12.82 m
