In a gas turbine, gas enters the turbine at a temperature of 600'C and 5 bar of pressure and exit at a pressure of 1 bar. This process is an adiabatic process but the change in entropy is 0.250 kJ/kg K. Determine the temperature of exit gas. Assumed that the gas is an ideal gas and take the value of y=1.3 and cp = 1.11 kJ/kg K. Sketch the process on a T-s diagram. Determine the temperature of the exit...

Air, modeled as an ideal gas, enters a turbine operating at steady state at 450 kPa, 800 K and exits at 100 kPa. The temperature of the exiting air is 420 K. a) If the turbine is well insulated and you can ignore kinetic and potential energy effects, determine if the exit temperature can be correct. b) What if the exit temperature is 550 K? Explain you’re your reasoning. Hint: Find the entropy generation rate first.

In a regenerative ideal Rankine cycle, hot water steam enters the turbine at 10 MPa and 480°C. condenser inlet pressure is 10 kPa. Some steam is taken from the turbine at a pressure of 0.7 MPa, feeds a Closed Feed water heater and is sent to the condenser as a saturated liquid at a pressure of 0.7 MPa at the outlet. The other outlet (cold) is at a pressure of 10 MPa and a saturation temperature of 0.7 MPa. According...

A simple Rankine cycle with a non-ideal turbine has the
following relevant states: - Water leaves the condenser as a
saturated liquid with a pressure of 100.0 kPa. - As it passes
through the ideal pump, it is raised to a pressure of 7 MPa. - The
boiler raises adds heat isobarically until the substance has a
temperature of 350∘C. - The turbine has an isentropic efficiency of
89.0%. - The mass flow rate through the system is 25 kg/s...

Air modeled as an ideal gas enters a turbine operating at steady state at 1040 K, 278 kPa and exits at 120 kPa. The mass flow rate is 5.5 kg/s, and the power developed is 1200 kW. Stray heat transfer and kinetic and potential energy effects are negligible. Assuming k = 1.4, determine: (a) the temperature of the air at the turbine exit, in K. (b) the percent isentropic turbine efficiency.
