Aturbine is fed water from a reservoir through a 1-ft diameter, 300-ft long pipeline. the reservoir water surface is 90 ft above the turbine centerline. free discharge occurs from the turbine through a 1-ft diameter pipe connected to its centerline. if the power developed by the turbine is 50 hp and the head loss in the system amounts to 35.8 ft, what is the flow rate? .

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?
