An assembly consist of two 15/64" thick plates at 6 1/2" knurled pipe, and a threaded rod insert through the plates and pipe. two 3/32" thick washers and a 3/4" thick hex nut are used on each end of the assembly . if 1/4" of threaded rod sticks out past the nut on each side of the assembly, what is the total length.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
