GATE ME 2000 | Rankine Cycle Question 34 | Thermodynamics

always given by $${\left( {\gamma RT} \right)^{{\raise0.5ex\hbox{$\scriptstyle 1$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}}}$$ where $$\gamma $$, $$R$$ and $$T$$ are respectively the ratio of specific heats, gas constant and temperature in $$K$$

always given by $${\left( {\partial p/\partial \rho } \right)_s}^{{\raise0.5ex\hbox{$\scriptstyle 1$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}}.$$ Where $$P,$$ $$\rho $$ and $$s$$ are respectively pressure, density and entropy

always greater than the velocity of fluid at any location.

GATE ME 1997

MCQ (Single Correct Answer)

-0.6

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

$$m{h_1} - \left( {{h_2} - {h_1}} \right)$$

$${h_1} - m\left( {{h_2} - {h_1}} \right)$$

$${h_2} - m\left( {{h_2} - {h_1}} \right)$$

$$m{h_2} - \left( {{h_2} - {h_1}} \right)$$
