Consider an actual regenerative Rankine cycle with one open feed water heater. For each $$kg$$ steam entering the turbine, if $$m$$ $$kg$$ steam with a specific enthalpy of $${h_1}$$ is bled from the turbine, and the specific enthalpy of liquid water entering the heater is $${h_2},$$ then $${h_3},$$ the specific enthalpy of saturated liquid leaving the heater is equal to
A
$$m{h_1} - \left( {{h_2} - {h_1}} \right)$$
B
$${h_1} - m\left( {{h_2} - {h_1}} \right)$$
C
$${h_2} - m\left( {{h_2} - {h_1}} \right)$$
D
$$m{h_2} - \left( {{h_2} - {h_1}} \right)$$
