A piston/cylinder assembly in a car contains 12 in3 of air at 13 lbf/in2 and 68 F. The air is compressed in a polytropic process with exponent n = 1.25 to a final volume six times smaller. Determine the final pressure and temperature, and the heat transfer of the process

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
