Physics · Mass Transfer
In a packed absorption tower operating under dilute conditions, the height of a transfer unit (HTU) is related to the molar flux per unit area G, overall gas-phase mass transfer coefficient KG, and the specific interfacial area a by:
- 1HTU = G × aKG
- 2HTU = GKG × a✓
- 3HTU = KG × aG
- 4HTU = 1KG × a
Correct answer
HTU = GKG × a
