Question
please solve the questions, if you know some of them that fine.
Write the intensive form of the energy equation for a closed system, Explain each term Explain iscntropic process and describe how thoes it differ from polytropic process? Draw an isothermal process on a p-v diagram calculate absoluate pressure at point P in the liquid (s = 0.8) tank shown. Explain Rfrigeration cycle using a block diagram A refrigeration cycle has Qout = 1000 Kj and W cycle = 200 kJ, determine the coefficient of performance beta of the cycle. Five (5) kg of air undergoes polytropic expansion process in a piston-cylinder asscembly from P1 = 100 kPa, vi = 0.04 m3/kg to v2 = 0.02 m3/kg. During the process p1v1 = p2v2 = constant, determine the work in KJ. Two (2) kg of oxygen undergoes a thernodynamic cycle consisting of the following processes; Consider negligible kinetic or potential energy changes
