Transcribed Image Text:

An open circular tank 5 m diameter contains benzene at 22 deg Celsius exposed to atmosphere in such a manner that the liquid is covered with air film of 0.9*10^-2 m thickness. The concentration of benzene beyond the air film is negligible. If benzene costs Rs. 80 per litre, calculate amount lost per day. Data: Vapor pressure of benzene at 22 deg Celsius 100 mm Hg diffusivity of benzene in air at 10 deg Celsius 0.77*10^-4 m^2/s Specific gravity of benzene =0.88 Viscosity of benzene at 0 deg Celsius 0.75*10^-3 kg/ms Viscosity of benzene at 25 deg Celsius=0.55*10^-3 kg/ms Kindly provide detailed solution and also if there is any diffusivity calculation with respect to temperature(two different temperatures 22 and 0 deg Celsius are used) please provide those calculations too.
