Water (10 kg/s) at 1 bar pressure and 50 C is pumped isothermally to 10 bar. What is the pump work? (Use the steam tables.) -7.3
kJ/s O 7.3 kJ/s -210 kJ/s e345 kJ/s 3451 kJ/s
1 answer:
Answer:
The pump work is 3451 kJ/s
Explanation:
Pump work (W) is calculated as
where
is the enthalpy of water at its final state
is the enthalpy of water at its initial state
is water mass flow
For liquids, properties are evaluated as saturated liquid. From the figure attached, it can be seen that

The arrangement of molecules within the 3 phases of matter are shown in the picture.
For the solid, the molecules are packed closely together. They don't have much space to move, so they just practically vibrate. For the liquid, the molecules are relatively farther from each other. The liquid molecules can flow freely but not as much as the gases. In the gases, the molecules are very far from each other. They are very sensitive to slight changes of pressure, volume and temperature.
