On a mollier diagram show all the stagnation and static points required to represent the complete flow process in a diffuser. air enters a diffuser with an average velocity of 375 m/s at a stagnation pressure and temperature of 360 kpa and 470 k respectively and leaves at a stagnation pressure of 300 kpa with an average velocity of 120 m/s and a static pressure of 280 kpa. determine (i) the static pressure and mach number of the air at inlet (ii) the diffuser efficiency, (iii) the mach number at exit and the overall entropy increase.

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

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
