2. The capacities of refrigeration units are commonly given in "tons", which corresponds to how many tons of ice the unit can make in 24 hours. Assume we have a 3-ton unit (this is a standard size for a residential heat pump). We can calculate how many kW of cooling capacity this corresponds to: The latent heat of fusion of water is 334 kJ/kg. ● 3-tons = 6000 lb = 2730 kg (2730 kg)(334 kJ/kg) = 911,800 kJ/24 hours = 10.55 kW of cooling. ● Assume you have a Carnot refrigerator that has the cooling capacity noted above and operates between ambient at 20°C and a cold space at 0°C. Find the amount of electric power that is required by the refrigerator (kW). Find the cost of the electricity needed to run this system for one day, using the current Seattle City Light rate of $0.13/kW-hr. Also find COPR.
Steam passes steadliy through a turbine and condenser as shown in the figure below. After expanding through the turbine and producing 1000kW of power, the steam is at a pressure of 0.08 bar and a quality of 87.4%; it enters a shell-and-tube heat exchanger where the steam now condenses on the outside of tubes through which cooling water flows; this condensate continues to flow, finally exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing steam is 58kg/s, In order to condense the steam, cooling water enters the tubes at 15°C and flows as a separate stream to exit at 35°C with negligible change in pressure. Stray heat transfer is negligible as are kinetic and potential effects. Considering the steam inside the turbine as a system, is the system best described as open, closed or isolated? What is the mass flow rate of steam entering the turbine in kg/s? What is the enthalpy at the inlet of the turbine in k/kg? What is the mass flowrate of the cooling water in kg/s?…
