Agas - turbine power plant operates on the simple brayton cycle between the pressure limits of 100 and 1600 kpa. the working fluid is air, which enters the compressor at 40 c at a rate of 850 m^3/min and leaves the turbine at 650 c. assuming a compressor isentropic efficiency of 85 percent and a turbine isentropic efficiency of 88 precent, determine (a) the net power output, (b) the back work ratio, and (c) the thermal efficiency. use constant specific heats with cv =.821 kl/kg*k , cp = 1.108 kj/kh*k, and k= 1.35.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
