QUESTION 1 A heat pump extracts heat from a cold temperature reservoir at 263 K at high temperature reservoir, an auditorium, at 298 K. The heat pump requires (a) Draw a schematic diagram of the heat pump a rate of Q, and rejects 8 kW of heat to a an input power of 2.5 kw system and the reservoirs and show all energies and their values and directions on the diagram. ing an energy balance on the system, determine the...

SP3. A Carnot engine operating in reverse as a heat pump moves heat from a cold reservoir at 7°C to a warmer one at 22°C. a) What is the efficiency of a Carnot engine operating between these two temperatures? b) If the Carnot heat pump releases 250 J of heat into the higher-temperature reservoir e co in each cycle, how much work must be provided in each cycle? c) How much heat is removed from the 7°C reservoir in each...

(12 pts) A heat pump operating on a cyclic process receives heat from a reservoir at 500°C and rejects the waste heat at a rate of 30 kW to the ambient air at 300 K. If the work output of the engine is 45 kw, determine if the cycle is possible, and if the cycle is reversible. Explain with calculations. Show calculations using both efficiency (Method 1) and Entropy generation (Method 2) analysis.

A steam power plant operates with high pressure oft 4 MPa and hasleel receiving heat from a 700°C reservoir. The ambient air at 20°C provides cooling to maintain the water/vapor mixture in the condenser at 60°C. All components are ideal i.e., reversible) except the turbine which has an efficiency 92% of a reversible, isentropic process. Other than the irreversibility of the turbine, the power plant can be considered as a Rankine cycle. Determine the following quantities in the suggested...

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...
