From the runs a fixed rpm and varying load, make a ‘willian’s line’ plot offuel rate versus brake horsepower. the extrapolation of the line through the datato a fuel rate of zero gives a (negative) brake horsepower that is thought torepresent the internal friction of the engine at that rpm (for both cycles). discuss how this internal and environment?

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

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
