Convection is faster than conduction?
A stream of air at 100 kPa pressure and 300 K is flowing on the top surface of a thin flat sheet of solid naphthalene of length 0.2 m with a velocity of 20 m/sec. The other data are:Mass diffusivity of naphthalene vapor in air = 6 * 10 –6 m2/secKinematic viscosity of air = 1.5 * 10 –5 m2.scConcentration of naphthalene at the air-solid naphthalene interface = 1 * 10 – 5 kmol/m3Calculate the overage mass transfer coefficient over the flat plate.Note: For heat transfer over a flat plate, convective heat transfer coefficient for laminar flow can be calculated by the equation.Nu = 0.664 ReL1/2 Pr1/3you may use analogy between mass and heat transfer.
In a wetted-wall tower, an air-H2S mixture is flowing by a film of water which is flowing as a thin film down a vertical plate. The H2S is being absorbed from the air to the water at a total pressure of 1.50 atm abs and 30oC. The value of kc of 9.567×10-4 m/s has been predicted for the gas-phase mass-transfer coefficient. At a given point the mole fraction of H2S in the liquid at the liquid-gas interface is 2.0×10-5 and pA of H2S in the gas is 0.05 atm. The Henry’s law equilibrium relation is pA(atm) = 609xA (mole fraction in liquid). Calculate the rate of absorption of H2S.
