During one cycle, the working fluid in an engine engages in two work interactions: 35Kj to the fluid and 62Kj from the fluid and three heat interactions: two of which are75Kj to the fluid and 56Kj from the fluid. Calculate the magnitude and direction of the third heat interaction. In a cyclic comprising of air compression and expansion, the initial and final work done by the prism during the compression stroke are 42Kj and 10.2Kj respectively and the heat rejected to the surrounding is 65Kj. During the expansion stroke work done by air on the prism is 8.4Kj. Determine the quality of heat transferred to or from the system. c).Why is renewable energy sources preferable in present day industrial, commercial and domestic space to non-renewable energy sources?
