1. Water with a density of ρ=1000 kg/m3 flows through a pump with a flow rate of 0.40 m3 /s. The pump inlet pipe is 0.2 m in diameter. At the inlet, the pressure is equal to atmospheric pressure. The pump outlet is 0.1 m in diameter and 2.0 m above the inlet. The outlet gauge pressure is 200 kPa. The system is isothermal and at steady state. a. Write the general form of the energy balance. Cancel out negligible terms, and state the keyword/assumption to justify. Simplify to the resultant energy balance. b. How much power does the pump add to the fluid?

Question

1. Water with a density of ρ=1000 kg/m3 flows through a pump with a flow rate of 0.40 m3 /s.
The pump inlet pipe is 0.2 m in diameter. At the inlet, the pressure is equal to atmospheric
pressure. The pump outlet is 0.1 m in diameter and 2.0 m above the inlet. The outlet gauge
pressure is 200 kPa. The system is isothermal and at steady state.


a. Write the general form of the energy balance. Cancel out negligible terms, and
state the keyword/assumption to justify. Simplify to the resultant energy balance.

b. How much power does the pump add to the fluid?
