MCQ (Single Correct Answer)

-0.6

Consider a steam power plant using a reheat cycle as shown. Steam leaves the boiler and enters the turbine at $$4$$ $$MPa,$$ $${350^ \circ }C$$ $$\left( {{h_3} = 3095\,\,kJ/kg} \right).$$ After expansion in the turbine to $$400$$ $$kPa$$ $$\left( {{h_4} = 2609\,\,kJ/kg} \right)$$, the steam is reheated to $${350^ \circ }C$$ $$\left( {{h_5} = 3170\,kJ/kg} \right),$$ and then expanded in a low pressure turbine to $$10$$ $$kPa$$ $$\left( {{h_6} = 2165\,kJ/kg} \right).$$ GATE ME 2004 Thermodynamics - Rankine Cycle Question 31 English

MCQ (Single Correct Answer)

-0.6

The efficiency of superheat Rankine cycle is higher than that of simple Rankine cycle because

the enthalpy of main steam is higher for superheat cycle

the mean temperature of heat addition is higher for superheat cycle

the temperature of steam in the condenser is high

the quality of steam in the condenser is low

For a compressible fluid, sonic velocity is

a property of the fluid

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.
