Wetted wall column is employed to separate 95% acetone from air - acetone mixture using pure water. gas flow rate is 2500 m hr and contains 7.5 volume % acetone. water flow rate is 3 kg/m' of pure air, temperature and pressure are 25 °c & i atm. calculate the necessary contact area (in m') if overall mass transfer coefficient is 0.35 kmol/m hr. (mole acetone mole air) the equilibrium relation is y -1.75 x

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
