Three hundred $k\frac{g}{m}in$ of steam enters a steam turbine at $350C$ and $40$ bar through a $7\mathrm{.}5-cm$ diameter line and exits at $50C$ and $10\mathrm{.}0$ bar through a $4\mathrm{.}5-cm$ line. The exiting stream may be vapor, liquid, or "wet steam", a mist composed of saturated water vapor and entrained liquid droplets.

How much power is transferred from the turbine to the steam? The answer is signed $($i$.$e$.$ can be positive or negative$).$

Neglect $E_p$ but not $E_k.$

$W=$

i

kW

What percentage of the total power is due to kinetic energy changes?

$\%$ kinetic energy
