An engine running on an Otto cycle has a compression ratio ry= 9 and a pressure at the end of the combustion process P3= 105 bar. Assuming isentropic expansion, determine the pressure at the end of the expansion stage (P4). You may assume the ratio of specific heats (y) is 1.4. The units of your answer should be "bars" and it should be accurate to 2 significant figures (eg X.X).
