A 4 kW motor is driving an oil pump with an efficiency of 95% down a 10 mm diameter pipe. If the velocities of the fluid down the pipe is 1.8 m/s

a) What is the flow rate that the pump delivers?

b) What is the pressure that the pump can deliver?

c) The viscosity of the oil is v = 0.00001 m2/s. Is the flow in the pipe laminar or turbulent?
