Problem $2$ A diffuser receives $0\mathrm{.}2k\frac{g}{s}$ steam at $500$kPa,$350C.$

The exit is at $1$MPa,$400C$ with negligible kinetic energy and

the flow is adiabatic.

$2$A$)$ At the inlet, identify the phase and find the specific volume

and the enthalpy.

$2$B$)$ At the exit, identify the phase and find the enthalpy.

$2$C$)$ Find the average velocity at the inlet.

$2$D$)$ Find the cross$-$section area of the inlet.
