In a large manufacturing plant, a pump is used to move a liquid fuel from a below-ground tank to a raised furnace. The total elevation change that the fuel experiences is 15 meters. The flow rate is 1.7 kg/s.

(a) If the fuel is ethanol ($\rho$ = 790 kg/m$^3$), what is the total pressure increase that the pump will need to impart on the fuel?

kPa

(b) If the fuel is ethanol, what is the minimum power required?

kW

(c) If the fuel is propane ($\rho$ = 500 kg/m$^3$), what is the minimum power required?

kW
