Air in a piston-cylinder assembly executes a Carnot power cycle (4 internally reversible processes, shown in the figure below). The isothermal expansion and compression processes occur at TH 1400 K and Tc-350 K, respectively. The pressure at the beginning and end of the isothermal compression are p4-100 kPa and pi - 500 kPa, respectively Assume the ideal gas model for the air: ai 0.717 J/g.K Mair- 28.97 g/mol kpv.air 1.4 R 8.314J /(mol K) Adiabatic Isothermal expansion Adiabatic compression Gas...

Need help for this Brayton Cycle problem.
Please help me
4. (30 marks) A gas-turbine power plant operates on the simple Brayton cycle between the pressure limits of 100 kPa and 800 kPa. The T-s diagram of this cycle is shown in Fig. 2. Air enters the compressor at 30°C and leaves at 330°C at a mass flow rate of 200 kg/s. The maximum cycle temperature is 1400 K. During operation of the cycle, the net power output is measured...
2. Isochoric/Adiabatic/Isobaric Cycle (10 pts) A heat engine using a monatomic gas follows the cycle shown in the PV diagram to the right. Between stages 1 and 2 the gas is at a constant volume, and between 2 and 3 no heat is transferred in or out, between 3 and 1 the pressure is held constant (a) For each stage of this process, calculate in Joules the heat, Q, transferred to the gas, and the work, W, done by the...
Consider a Carnot cycle in which the working substance is 0.10 mol of perfect gas molecules, the temperature of the hot source is 373 K, that of the cold sink is 273 K; the initial volume of gas is 1.00 dm', which doubles over the course of the first isothermal stage. For the reversible adiabatic stages it may be assumed that VT3/2 = constant. a) calculate the volume of the gas VB and Vc); b) calculate the volume of the...
