Relative volatility varies with the concentration of component for an ideal solution. The relative volatity of a binary mixture may be defined as the ratio of vapor pressure of component 'A' to that of component 'B', when
Statement 1: Diffusion of gas component through the resistive film to the bulk of the liquid is the rate determining step. Statement 2: Diffusion of gas component through the gas-liquid inter-phase is the rate determining step.
Consider the following pairs. S. No. Dispersed Phase Dispersing Medium Type 1. Liquid Gas Aerosol 2. Gas Liquid Foam 3. Liquid Liquid Emulsion 4. Liquid Solid Solid Sol   Which are the correct pairs?
When the liquid phase and vapour phase of a binary system obeys Raoult's and Dalton's law respectively, the relative volatility is the ratio of
In a wetted-wall tower, an air-H2S mixture is flowing by a film of water which is flowing as a thin film down a vertical plate. The H2S is being absorbed from the air to the water at a total pressure of 1.50 atm abs and 30oC. The value of kc of 9.567×10-4 m/s has been predicted for the gas-phase mass-transfer coefficient. At a given point the mole fraction of H2S in the liquid at the liquid-gas interface is 2.0×10-5 and pA of H2S in the gas is 0.05 atm. The Henry’s law equilibrium relation is pA(atm) = 609xA (mole fraction in liquid). Calculate the rate of absorption of H2S.
In a newly developed innovative idea brought up by CSIR in India, gas turbine exhaust gas are being utilized to convert feedwater into steam. Certain data of the experiment are as follows: mass flow rate of exhaust gas = 40 kg/hr, enthalpy of exhaust gas at the time of their exit from gas turbine is 600 kJ/kg, steam turbine output as measured by brake dynamometer = 60 hp-sec, thermal efficiency of steam power plant is 0.25, efficiency of exhaust gas in converting feedwater into steam is taken as 50%. Find the enthalpy of exhaust gas remaining after they generate steam from feedwater?
Mixture A and Mixture B contain consist of 40 liters and 60 liters of mixtures of liquids X and Y in different proportions. Quantity of liquid X in mixture A is 10 liter less than the quantity of liquid X in mixture B. The total quantity of liquid Y in both the mixtures is 40 liters. If 30% of liquid is taken from mixture A and put into mixture B, then what will be the ratio of liquid X to liquid Y in mixture B?
