5. In an ideal Rankine cycle, steam is generated at 4.1 MPa and 480 °C. The condenser is at 32 °C. Determine (a) the ideal pump work and (b) the cycle thermal efficiency. (c) For an engine with the same end states, determine the thermal efficiency, and steam rate (d) Considering the engine only, assume the brake engine efficiency to be 78%, the generator efficiency 92%, the steam flow rate 163,000 kg/hr; compute the output of the combined unit.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
Q1: If a calorimeter is not assumed to be adiabatic, how would one calculate the heat transfer? Guide Questions: What are the parameters to be considered and the equations to be used? What law of thermodynamics does this transfer of heat to the surroundings touch? Is an adiabatic system automatically considered as a closed system? Please help me understand by also attaching a reference/book/journal article. This would help me in my essay. Thank you.
