An air-standard otto cycle has a compression ratio of 6 and the temperature and pressure at the beginning of the compression process are 5208r and 14.2 lbf/in.2, respectively. the heat addition per unit mass of air is 600 btu/lb. determine (a) the maximum temperature, in 8r. (b) the maximum pressure, in lbf/in.2 (c) the thermal efficiency. (d) the mean effective pressure, in lbf/in.2

On a average work day more than work place firs are reorted

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

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
