Exercise $2$: Consider the schematic below. Annotate the control volume$($s$)$ and list analysis steps to determine:

a$)$ the power required by the pump, in kW $,$ to supply water to the inlet of the mixing chamber.

b$)$ the mass flow rate of steam. in $k\frac{g}{s},$ that flows through the turbine.

a$)0=Q$

Wov $=$

$\frac{oF}{ot}=Q_{cv}-$wev$+m$
