Question 2.
Consider a pump that is used for increasing the pressure of water in a piping system so that a fountain is created in a pool. The piping system is composed of 10 m of 0.045 m diameter commercial steel pipe, five long-radius flanged 90\deg elbows, and two fully open gate valves. If the flow velocity at the exit of the piping system is 3(m)/(s), calculate
the work done by the pump per unit mass of water and
the pressure rise generated by the pump. Assume that the flow is accelerated efficiently from the reservoir to the pipe. The density and the viscosity of water are 1000(kg)/(m^(3)) and 0.001N(s)/(m^(2)), respectively, and the gravitational acceleration is 9.81(m)/(s^(2)).
