A 0.8 liter of boiled water at 100C is poured into an adiabatic mug in an air-conditioned hotel room of 25C. An educational Stirling engine is placed onto the mug, whereby it receives the heat from the boiled water, and begin to rotate the wheels. The density and specific heat of the water is 1000 kg/m and 4.184 kJ/kg.K, respectively. By assuming the atmospheric pressure is equal to 101.42 kPa, and about 90% of the heat is released to the atmosphere through the engine, determine: (a) The amount of heat that is transferred to the engine. (b) The amount of heat that is transferred to the atmosphere. (c) The amount of work that is done by the engine. (d) According to the Carnot Principle, will the Stirling. engine works according to the given parameter? Qout Wout
