Effect Of Concentration On The Mass Transfer Coefficient In The Liquid Film, Marvin Baker Schaffer, Philip Major Pomerantz
Effect Of Concentration On The Mass Transfer Coefficient In The Liquid Film, Marvin Baker Schaffer, Philip Major Pomerantz
Theses
The effect of liquid concentration on the resistance to mass transfer across the liquid film is studied for an acetone-methyl isobutyl ketone-air system in a packed tower. The liquid film resistance is computed by measuring the overall resistance for various concentrations and subtracting the gas film resistance. The gas film resistance is determined at the same liquid and gas rates by measurements on the pure components.
In the theory developed to handle the calculations, it is assumed that the interface temperatures are the wet-bulb temperatures based on a dynamic equilibrium. This supposition is supported experimentally at a liquid rate of …

Liquid-Gas Flow In Venturi Meter And Sharp Edged Orifice, Frank John Chwalek
Theses
The results of a study of pressure drops across a 5/32 inch throat venturi meter and a 5/32 inch thin plate sharp-edged orifice for the horizontal cocurrent, flow of the air-water two-phase two-fluid system in a 3/4 inch pipe under essentially isothermal conditions, are presented. This is the first critical study of two phase flow in a Venturi meter and. in a 5/32" orifice.
Flows of water of 0.1 to 1.7 gallons per minute with air rates in range of 0.00022 lbs/sec. to 0.0092 lbs/sec. of air mixed in were studied. All flows were turbulent when judged with the conventional …
