question

Find the sublimation rate of a uranium hexafluoride UF_6 cylinder7 mm. diameter when exposed to an air stream flowingat a velocity of 3.5 m/s. The bulk air is at 65°C and 1 atm. pressure.The surface temperature of the solidis 40°C at which its vapor pressure is 410 mm. Hg (54.65kN/m^2). The average heat transfer coefficient of fluid flowing perpendicularto a circular cylinder for fluid Reynolds number between1 and 4000 is given by Nu = 0.43 + 0.532 (Re)^0.5(Pr)^0.31 whereNu and Re are calculated with the cylinder diameter andfluid properties at mean temperature of cylinder and bulk-fluid.
