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

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

Replacing

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

i think its 100.
