Water flows past a flat plate that is oriented parallel to the flow with an upstream velocity of 0.5 m/s. Determine the ap- proximate location downstream from the leading edge where the boundary layer becomes turbulent. What is the boundary layer thickness at this location

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?
