An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2. At the beginning of the compression process, air is at 95 kPa and 27 degrees celcius. For a heat addition qin = 913.9 kJ/kg and a heat rejection qout = 353 kJ/kg assuming constant specific heats at room temperature
a) show the process on a T-s diagram
b) determine the net work output (wnet,out)
c) determine the thermal efficency of the cycle
d) determine the mean effective pressure (MEP) defined by the expression below.
MEP = wnet/(v1-v2). v1= maxmimum air specific volume and v2 is minimum air specific volume.
