question

A volatile fuel when spilled on a large flat surface quickly spreadsover a depth 1/4 in. and a length of 7 ft. The fuel is at60°F with a vapor pressure of 2psiahas the physical propertiesѵ = 10^-5 ft / sec, \rho = 54lb_m/ ft^3 and D_AB = 0.55 ft^2 / hr. The kinematic viscosity of air is 1.62 × 10^-4 ft^2 / sec.If a breeze at 75°F blows parallel to the fuelsurface at 15 mph, determine the evaporation rate.
