2. (i) In a regenerative Rankine cycte, the enthalpies (all in kJ/kg ) of steam at various stations (following the schernatic in erib sheet) are given: h1192,h4=640,hs=3456,h52942,h7=3456. If the pump works are negligible and the total steam mass flow rate in the cycle is 100kg/s, caleulate the steam mass flow rate extracted from the turbine (in kg/s ), the turbine power (in kW), and the cyele thermal efficiency. (ii) In a caicade refrigeration system, the mass flow rate of refrigerant in the upper cycle is 0.2 kg/s and the enthalpy change across its evaporator is 138kJ/kg. If the enthalpy change across lowerdenser of the lower cycle is 195kJ/kg, calculate the mass flow rate of refrigerant in the
