A 4 kW motor is driving an oil pump with an efficiency of 95% down a 10 mm diameter pipe. If the velocity of the fluid downs the pipe is 1.8 m/s,
1. What is the flow rate that the pump delivers?
2. What is the pressure that the pump can deliver?
3. If a 25 mm bore hydraulic cylinder is connected to the pipe, what would the forward stroke speed of the cylinder be?
4. The viscosity of the oil is v = 0.00001 m2/s. Is the flow in the pipe laminar or turbulent?
