Theory+ Problem 1& 2 on Kelvin Planck statement & Clausius statement, Second law of Thermodynamics

1. What is Kelvin-Planck statement and Clausius Statement? 2. Solve 1 problem for Kelvin-Planck statement and Clausius Statement each. A reversible engine is supplied with heat from two constant temperature sources at 900 K and 600 K and rejects heat to the constant temperature sink at 300 K. The engine develops work equivalent to 90 kJ/s and rejects heat at the rate of 56 kJ/s Estimate 1. Heat supplied by each source 2. Thermal efficiency of the engine A domestic food freezer maintains a temperature of -15°C . The ambient temperature is 30°C The heat leaks into the freezer at 1.75 kJ/s What is the minimum power necessary to pump the heat out? Please refer my following Playlists , Links are given: 1.
