Mass Transfer For the gas absorption, the height of a transfer unit, based on the gas phase is given by (G: superficial molar gas velocity, L: superficial molar liquid velocity, FG:mass transfer co-efficient, mols/m² , a: in-terfacial area per unit volume of tower) (G.a)/FG L/(FG.G) F/(FG.a) FG/(G.a) (G.a)/FG L/(FG.G) F/(FG.a) FG/(G.a) ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In a packed tower, the value of HETP equals HTUOG, when the equilibrium and the operating lines are (where, HETP = height equivalant to a theoretical plate HTUOG = overall gas phase height of a transfer unit) Parallel Straight Both A & B Neither A nor B Parallel Straight Both A & B Neither A nor B ANSWER DOWNLOAD EXAMIANS APP
