An ideal air standard brayton cycle operates at steady state with compressor inlet conditions of 300 K and 100 kPa and fixed turbine inlet temperature of 1700 K. for the cycle: a) Determine the net power developed per unit mass flowing in kJ/kg, and the thermal efficiency for a compressor pressure ratio of 8.
b) Plot the net power developed per unit mass flowing , in KJ/kg , and the thermal efficiency, each versus compressor pressure ratio ranging from 2 to 50.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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
