Q// Upon completion of the Reynolds experiment, we had this information. The tube diameter was 0.03 m, the flow rate 21*10^-6 Q (m ^ 3 / s) and the lamellar bisection type 'Find Re, viscosity and velocity m / s at a temperature of 26 ° C for water.

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?
