yale L 15 A gas power cycle uses air as the working fluid and has two turbine sections as shown in the figare below. The power produced by Turbine I is used to drive the compressor, and Turbine 2 produces output power W. Air enters the compressor with a semperature of 290 K and a mass flow rate of -2 (kgs] (State I); the air exits the compressor at 44SK (State 2). Heat is transferred from a high- temperature thermal reservoir, Ta- 1400 [K), to Heat Exchanger 1 at a rate Q,- The lemperature of the air is raised to 1100 [K] (State 3) as it flows through Heat Exchanger 1. The air enters Turbine I where it is expanded to State 4. The flow then proceeds to Turbine 2 and exits with a temperature of 500 (K] (State 5). Heat is then removed from the air through Heat Exchanger 2 at a rate Q which is rejectod to the low-temperature thermal reservoir, TL-200 (K). (A) Determine the temperature at the inlet to Turbine 2, Te (b) Calculate the power output from Turbine 2, W. (e) Calculate the rate of…

3 (a) A simple Rankine cycle uses water as the working fluid (Figure Q3). IA 9 in 4s 4 gout Figure Q3. Rankine Cycle The boiler operates at 7,000 kPa and the condenser at 100 kPa. At the entrance to the turbine, the temperature is 450 °C. The isentropic efficiency of the turbine is 90%, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 9.6 °C. The boiler is sized for a mass flow rate of 20 kg/s. Determine, (i) The rate at which heat is added in the boiler, (ii) The power required to operate the pumps, (iii) The net power produced by the cycle, (iv) The thermal efficiency. (b) After a long walk in the 14 °C outdoors, a person wearing glasses enters a room at 25°C and 60% relative humidity. (i) What is the difference between specific and relative humidity? (ii) Please explain whether the glasses will become fogged or not and why. An
