Air containing 20.0mole% water vapor at an initial pressure of 1 atm absolute is cooled in a 1-l sealed vessel from 200°c to 15°c. a)what is the pressure in the vessel at the end of the process? (hint: the partial pressure of air in the system can be determined from the expression pair = nairrt/v.) b)what is the mole fraction of water in the gas phase at the end of the process? c)how much water (grams) is condensed?

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
