Refrigerant 134a is compressed at steady state from initial state 1 to final state 2. The initial state conditions are 2.4 bar and 1ưC, whereas the final state conditions are 12 bar and 50ưC. The power input to the compressor is 2.6 kW. Neglect kinetic and potential energy changes. Determine the mass flow rate of 134a, in kg/min, assuming that no heat is crossing the control volume boundary.
