A venturi meter reduces the pipe diameter from 10 cm to 5 cm. Calculate the flow rate and mass flow assuming ideal condition.

10 Pump test system problem:. For the pump test arrangement shown in figure below, determine the mechanical efficiency of the pump if the power input is measured to be 3.85 hp when pumping 500gal/min of oil (y = 56.0 lb/ft3).
