please post step by step explanation
Consider a refrigeration cycle, as shown schematically below. The cycle uses R152a (1,1-difluoroethane i.e. CH3CHF2 ) as working medium. Up to now your company has used the Lee-Kessler tables and charts to thermodynamically model the system but you would like to improve the accuracy of the results by using the Peng-Robinson equation of state. \# 1.1. The outlet of heat exchanger HX01 is a saturated liquid. To specify the equipment, you need to know what the saturation pressure of the refrigerant is at a set temperature. Complete the 13.8\%. algorithm that can be used to determine the vapour pressure of R152a for a range of temperatures. The algorithm is given below and answers must be provided on the answer sheet attached. [9] + 1.2. Consider the compressor C01. The compressor has an isentropic efficiency of 75%. You would like to calculate the amount of work required by the compressor for a set pressure increase. Provide a step by step procedure as to how you would approach calculating the real amount of Work that the compressor requires. No calculations or equation of state specific equations are required, only the procedure and general equations. Importantly, assume that expressions for the residual enthalpy and entropy are available in terms of molar volume, temperature and EOS parameters i.e HR=f(T,V, EOS parameters ) and SR=f(T,V,EOS parameters ). All 1.3. Consider the evaporator (HX02). The stream exiting V01 and thus entering HX02 is at 20C and has a vapour fraction of 0.23 . If the stream exiting HX02 is a saturated vapour, estimate the amount of energy the refrigeration cycle can absorb per mole refrigerant cycled. Use the LeeKessler charts to conduct the estimation. Assume the heat exchanger operates isobarically. [11]
