What does the number of transfer units NTU signify? Do you want to have a small height of transfer unit HTU? How can you reduce the HTU? What is the effect on tower operation of the heat of absorption? You are given an overall mass transfer coefficient, based on gas side driving force of 0.08 cm/sec. You use this in a tower where the area/volume is 6.6 cm - 1 and the gas flux 7.10 - 4 mol/cm 2 sec. What is the HTU (based on the gas side driving force)?
