The vapor pressure of benzene is found to obey the empirical equation : ln(p/torr) = 16.725 - 3220.86k/t -118345k^2/t^2 from 298.2k to its normal boiling point 352.24k. given that the molar enthalpy of vaporization at 353.24k is 30.8kj/mol and that the molar volume of liquid benzene at 353.24k is 96.0 cm^3/mol, use the above equation to determine the molar volume of the vapor at its equilibrium pressure at 353.24k and compare this value with the ideal-gas value.

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
