At the same gas flow rate, the pressure drop in a packed tower being irrigated with liquid __________ that in dry packed tower.
-
Molarity is defined as the number of gm moles of solute per __________ of solvent.
-
The value of Lewis number (Le = Sc/Pr) for air-water vapour system is around
-
An aqueous solution of methanol is to be distilled in a tray column. High pressure steam is available as a source of heat. For a given reflux ratio and overhead composition, two options are being explored; (i) a reboiler is used and (ii) no reboiler is used but steam is fed directly to the bottom of the column. As compared to option (i), in option (ii)
-
