Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

Question

Thermodynamic

Carbon dioxide enters a compressor at T1=271 K and P1=100 kPa with a mass flow rate of
0.61 kg/s. The pressure ratio and the isentropic efficiency of the compressor is 4.9 and 80%,
respectively. AS shown in figure, carbon dioxide leaving the compressor is cooled to T3=360
K by a liquid water in a heat exchanger. If the inlet and outlet temperatures of the cooling
water are T4=20°C and T5=43°C respectively, calculate the required mass flow rate of
cooling water, in kg/s.
Properties of CO2: C,=0.895 kJ/(kgK), Cp=0.706 kJ/(kgK), R=0.1889 kJ/(kgK), k=1.268
Properties of water: C,=4.178 kJ/(kg°C)
