Saturated Steam at $30$ bars is contained in a cylinder with piston which has initial volume of $0\mathrm{.}03$ meter cube $.$The steam is cooled at constant volume until the temperature reaches $200$ degree celsius $.$The steam is then expanded isothermally until volume $=2($intial Volume $).$Calculate pressure for state $2$ and enthaply $.$Change from $1$ to $2$ and $2$ to $3$ state.
