wrte the energy and entropy balances for the Heat Transfer Limited (HTL) Camot cycle. Assume the HTL Carnot cycle is intemally reversible and extemally irreversible. The HTL Carnot cycle operates between a heat source temperature, TH600K, and heat sink temperature, T 300K. Assume the overall heat transfer coefficient multiply by the heat exchanger area (UA) of the high and low temperature heat exchanger are equal, i.e, UA UA, = 10 kW/K Using the LaGrange Multipliers method to find the maximum...

Problem 7: (15 pts) An ideal air-standard Brayton cycle operates steadily with pressure limits of the cycle are 100 kPa and 800 kPa. The temperature at the exit of turbine is 500 K. During the heat rejection process, heat is released from the cycle at a rate of 320 kW and the mass flow rate is 2 kg/s. The air is treated as an ideal gas with constant specific heats, i.e. k = 1.4 and R = 0.287 kJ/(kg ·...

(Clausius Inequality) A thermodynamic cycle operates at steady state between reservoirs at 1000 K and 500 K. The cycle receives energy via heat transfer at the high temperature at a rate of 1500 kW and discharges energy via heat transfer to the cold reservoir. a. The cycle develops power at a rate of 1000 kW. Use the Clausius inequality to determine whether this cycle operates reversibly, irreversibly, or is impossible. b. Do the same as in part a, but now...

A steam power plant operates on a simple ideal Rankine cycle between the pressure limits of 6 MPa and 50 kPa. The temperature of the steam at the turbine inlet is 450◦C, and the mass flow rate of steam through the cycle is 50 kg/s. (a) Find the temperature, pressure and specific volume at states 1, 2, 3, and 4. (b) Find the heat supplied, heat rejected, work consumed by the pump, work produced by the turbine, net power generation,...

A power cycle operates between a lake’s surface water at a temperature of 300 K and water at a depth whose temperature is 285 K. At steady state the cycle develops a power output of 10 kW, while rejecting energy by heat transfer to the lower temperature water at the rate 14,400 kJ/min. Determine (a) the thermal efficiency of the power cycle and (b) the maximum thermal efficiency for any such power cycle. I have no idea on how to...
