n an educational institution, cold drinking water ( liquid ) is needed during the summer. in this regard, a water-cooling system is installed on campus, and it needs to handle a water volumetric flow rate of 0.015 m3/s. The outlet temperature of the cooler is set at 10'C . A refrigerator cycle is employed to cool the water and the refrigerator is driven by a steam turbine, as shown in the figure below. During the installation , it was also found the outside conditions tend to heat the water at a rate of 10kW (Qa). For the proposed set up , find the following volumetric flow rates at the inlet and outlet of the turbine. Work done by the turbine . Rate of the heat removal from the cooler (Q1) heat removal from the cycle ( Qn ) and expected COP of the refrigeration cycle. Entropy change for the processes. Assume reversible adiabatic expansion in the turbine and reversible process in the cooler. Neglect the kinetic and potential energy charge in the turbine. Use zeroth order interpolation wherever necessary. present your final answer in SI units.
