Refrigerant 134 A enters in a condenser of a heat pump at 180 kPa and -4 0C and exits with a quality of 0.8 and the same pressure of 180 kPa. The mass flow rate of the refrigerant is 65 kg/h, and the heat pump compressor consumes 45 kJ/min of power. Determine the coefficient of performance of the heat pump. Type your answer in the first box.
A completely insulated mixing vessel is designed to deliver water at 60 ⁰Cand atmospheric pressure at a rate of 4 kg/s by mixing two streams of incomingwater in an environment at 25 ⁰C. Saturated steam at atmospheric pressure isinserted on the hot side. Two options are being considered for the cold side: (a)chilled water from the plant at 3 ⁰C or (b) water from the tap at 20 ⁰C (both atatmospheric pressure). 1.

An electric water heater is fed with an input stream of 15.0 kg/min of water at 17.5°C. Hot water is then provided as two different output streams, one at 43.0°C and the other at 60.0°C. The volume of the water in the tank remains constant and the mass flowrate of the outlet stream at 43.0°C is 10.5 kg/min. Perform the following activities, i. Draw a detailed flowchart for this process with all given information. ii. Calculate the power, Q (in kW) that the electric heater must provide in order to keep the temperatures of the outlet streams at 43.0°C and at 60.0°C, respectively. You must write the mass and energy balances and show your calculation.
