Solution
The specific work (w) done by the pump can be calculated using the formula:
w = h2 - h1
where h1 and h2 are the specific enthalpies of the water at the inlet and outlet of the pump, respectively.
Since the process is adiabatic, there is no heat transfer and the change in specific enthalpy is equal to the specific work done by the pump.
To find the specific enthalpies, we can use steam tables for water at the given temperatures and pressures.
However, without the specific enthalpy values at the given conditions, we cannot calculate the specific work.
Please provide the specific enthalpy values or use the steam tables to find them.
