It is desired to construct a drier for removing $100$ lb of water per hour. Air

is supplied to the drying chamber at a temperature of $66$ deg C$,$ a pressure of $760$ mm Hg$,$ and a dew point of $4\mathrm{.}5$ deg $*$ C If the air leaves the drier at a temperature of $35$ deg $*$ C a pressure of $755$ mm Hg$,$ and a dew point of $24$ deg C$,$ calculate the volume of air, at the initial conditions, that must be supplied per hour.
