4 An air nozzle has an efficiency of .90 and is adiabatic. air enters at p1=200 kPa, T1=1300 K with negligible velocity. air exits at p2=130 kPa. use dead state variables of T0=293 k and P0= 100 kPa and a variable heat capacity. what is t2 and the rate of exergy destruction?

Please answer this problem

Need ASAP thank you.

Steam enters the first turbine at (80 B: 567.669 KJ/Kg bar), (480 °C) and expands to (7 bar ). The steam is reheated to (440 °C) C: 565.669 KJ/ Kg before entering the second turbine, it expands to the condenser pressure of (8 KPa). The net power output of the cycle is (80 MW). * 22- The entropy of point 10 is * A: 1.56716 KJ/Kg.k Suam B: 1.6716 KJ/Kg.k C: 1.7716 KJ/Kg.K Cundetnet CS ALPa Closed heater Open 23- The enthalpy of point 11 is * 20Ss T20°C 10 12 13 Pump 1 A: 872.357 KJ/Kg Pump 2 Trap B: 882.357 KJ/Kg Fig 4.1 A reheat - regenerative vapor power cycle C: 892.357 KJ/ Kg

Q2. Thermal power station contains three units, one 700kw and two units with 500kw for cach one. The fuel consumption is 0.5kg/kwh and the calorific value of fuel oil is 12000kcal/kg. If the plant capacity factor is 40%, estimate : 1. The fuel oil required for a week. 2. Overall efficiency.

Q.1 A piston-cylinder device operates 1 kg of fluid at 20 bar pressure. The initial volume is 0.1 (the last digit of your id.no). The fluid is expand reversibly following the process pv¹.3 = constant. at point B the volume becomes 1.5 m³. The fluid is then cooled at a constant temperature. Calculate the work done in the cycle. p (bar) 0.1 last digit of your id. no 0.1 v cu.m Py ¹.3 B 1.5
