Mechanical Engineering

1) A pump steadily delivers 15.9 kg/s of water at the conditionsgiven below. Calculate the pump power (kW).

There is no heat transfer from the pump to the surroundings(i.e., adiabatic conditions).

Pump Inlet Temperature = 20oC

Pump Inlet Pressure = 196 kPa

Pump Inlet Diameter = 10 cm

Pump Inlet Elevation = 22.7 m

Pump Exit Temperature = 20oC

Pump Exit Pressure = 400 kPa

Pump Exit Diameter = 10 cm

Pump Exit Elevation = 45.4 m

2) A pump steadily delivers 16.3 kg/s of water at the conditionsgiven below. Calculate the pump power (kW).

There is no heat transfer from the pump to the surroundings(i.e., adiabatic conditions).

Pump Inlet Temperature = 20oC

Pump Inlet Pressure = 107 kPa

Pump Inlet Diameter = 11 cm

Pump Inlet Elevation = 20.1 m

Pump Exit Temperature = 20oC

Pump Exit Pressure = 380 kPa

Pump Exit Diameter = 4.2 cm

Pump Exit Elevation = 44.9 m
