(1) A four-cylinder engine has a compression ratio of 8, and cach cylinder has a maximum volume of 0.6 L. At the beginning of the compression process, the air is at 98 kPa and 17°C, and the maximum temperature in the cycle is 1800 K., dctermine (a) the amount of heat supplied per cylinder. (b) the thermal efficiency, and (c) the number of revolutions per minute rcquired for a net power output of 60 kW. Study the effect of varying the compression ratio from 5 to 11 on the network done and the efficiency of the cycle. Plot the P-v and T-s diagrams for the cycle, and discuss the results.

Draw a PV diagram for a Stirling cycle in which 40g of Ar (treated as an ideal gas) is isothermally expanded from 3L to 12L at a tem- perature of 650K. The sample is then undergoes isochoric cooling to 298K. The sample is then isothermally compressed to 3L and finally undergoes isochoric heating back to 650K. Label the states 1-4 on the graph.
