3. A heat engine operating between a geothermal steam source at 205°C and a riv-er at 18°C achieves an efficiency of 22%. What percentage of its theoretical max-imum efficiency is it achieving? 5. A certain engine is filled with gasoline that contains chemical energy nwhen the engine is started, it begins transforming that chemical energy intesmechanical energy. Over the course of a few seconds, the engine transforms8,000J of chemical energy, but 4,000) of that energy is 'wasted' in the form ofthermal energy.2 How much energy does the engine transform into useful mechanicalenergy during these few seconds?b. Calculate the efficiency of this engine.

Energy Flux Malaysia has just launched a new type of house refrigerator system using R-134a as a working fluid. It is claimed that the refrigerator can maintain the temperature of the refrigerated space at -35°C by rejecting heat to the surrounding air that enters a well-insulated condenser at 17°C and leaves at 27°C. The refrigerant enters the well-insulated condenser at 1.2 MPa and 60°C at a rate of X kg/s and leaves at the same pressure at 44°C. In an effort to attract consumers, silence mode feature is introduced where noise generated from the compressor unit is significantly reduced. Due to this new feature, the refrigerator is believed to consume 50% more actual power input when operated at Y kW. As an intern hired by the manufacturer, you have been tasked to perform the followings: a. Illustrate the above cycle with appropriate labels. Based on the information in TABLE Q1, calculate the mass flowrate of the surrounding air entering the heat exchanger in kg/s and determine the…
