Question $3$

$($Marks: $25)$

Two kg water at $200$ kPa with a quality of $25\%$ has its temperature raised $20C$ in a constant

pressure process. What are the heat transfer and work in the process?

Q$\mathrm{.}3\mathrm{.}1$ Draw the Pressure$-$Volume graph of the process.

Q$\mathrm{.}3\mathrm{.}2$ Draw the Temperature$-$Volume graph of the process

Q$\mathrm{.}3\mathrm{.}3$ What is the work done in the process?

Q$\mathrm{.}3\mathrm{.}4$ What is the heat transfer in the process?
