How to Calculate Diffusivity by Twin Bulb Method?
Diffusivity by Twin Bulb Method calculator uses Diffusion Coefficient = ((Length/(Inner Cross Section Area*Diffusion Time))*(ln(Pressure/(Partial Pressure of component A in 1-Partial Pressure of component A in 2))))/((1/Volume of Gas 1)+(1/Volume of Gas 2)) to calculate the Diffusion Coefficient, The Diffusivity by Twin Bulb Method formula is defined as diffusion coefficient calculation by the using of the experimental data of twin bulb's apparatus. Diffusion Coefficient is denoted by D_{AB} symbol.
How to calculate Diffusivity by Twin Bulb Method using this online calculator? To use this online calculator for Diffusivity by Twin Bulb Method, enter Length (L), Inner Cross Section Area (a), Diffusion Time (t), Pressure (P), Partial Pressure of component A in 1 (P_{A1}), Partial Pressure of component A in 2 (P_{A2}), Volume of Gas 1 (V_{1}) & Volume of Gas 2 (V_{2}) and hit the calculate button. Here is how the Diffusivity by Twin Bulb Method calculation can be explained with given input values -> 2.079442 = ((3/(0.1*1000))*(ln(800/(500-400))))/((1/50)+(1/100)).
