- An Aircraft air conditioning system comprises of a reciprocating compressor and during thecompression process a refrigerant gas is compressed. The cylinder is initially at a volume of 0.05m3 and contains 0.1 kg of ammonia at a pressure of 3 bar.The gas is subjected to a reversible adiabatic compression process to a final volume of 0.01 m3.Assuming the ammonia to be a perfect gas, calculate:Its initial temperature, pressure at the end of the compression stroke and the work done incompressing the ammonia.For ammonia: R = 530 J/kgK and cv = 166 J/kgKThe working substance for a carnot cycle is 8 lb of air. the volume at the beginning of isothermal expansion is 9 cubic feet and the pressure 300psia. the ratio of expansion during the addition of heat is 2 and the temperature of the cold body is 90 degree farenheit. Find (a) Qa,(b) Qb,(c) V3,(d) P3,(e) V4,(f) P4,(g) Pm, (h) the ratio of expansion during the isentropic process, and (i) the overall ratio of compression.I need help on the following question: The vapour compression cycle (picture provided), utilises the refrigerant R134a flowing at 0.05 kg s-1. Assuming that the compression is adiabatic and reversible. If the actual input power to the compressor is 2 kW, then: 1. You need to determine the theoretical input power to the compressor and the heat transfer (Φ) to theevaporator. Take the enthalpies h1, h2, and h3 to be 238.41, 263.68 and 81.5 kJ kg-1 (use the 'NH3 Refrigeration Table' where you can find online). 2. You need to determine the coefficient of performance based on your answer to the previous question (1). 3. You need to determine the compressors mechanical efficiency.
- A certain Geothermal Power Plant shows that 1,700,000 kg/hr of pressurized ground water is available at 17.5MPa and 330°C. The water will be throttled to a pressure of 1.7MPa to produce wet steam and this mixture will be passed through a water separator to remove the water droplets so that saturated steam at 1.7MPa is available at the entrance of the Turbine. Other data are as follows: Discharge Pressure of turbine = 85kPa-Vac; Turbine Efficiency = 73%. Mechanical Loss = 2% of shaft power. Generator Efficiency = 95%. Determine the following: 1.The mass flow rate, in kg/min, of steam entering the turbine. a. 153,720 b . 76,858 c. 38,430 d. 19,200 e. 9,350 2. The maximum amount of power, in kW, that the plant can generate. a. 38,430 b. 19,200 c. 76,858 d. 9,350 e. 153,720Air with mass flow rate of 1 kg/s enters the first stage of a compressor at 100 kPa and 300 K and exit the second stage of the compressor at 2677 kPa. If the compressed air outgoing from the first stage of the compressor passes through an intercooler, then enters the second stage of the compressor at temperature 353 K. What is the indicated isothermal efficiency for the compressor assuming ideal compression process with polytropica index n = 1.3 for both stages, no pressure loss in the intercooler, and the pressure ratio across the first and the second stage of the compressor are equal?One tenth Kilogram of a gas in a piston-cylinder assembly undergoes a Carnot power cycle for which the isothermal expansion occurs at 800K. The change in specific entropy of the gas during the isothermal compression, which occurs at 400K, is -25 kj/kg*K. Determine (a) the net work developed per cycle in KJ and (b) the thermal efficiency.
