# How do I find my Hatta number?

## How do I find my Hatta number?

For a second order reaction (rA = k2CBCA), the maximum rate of reaction assumes that the liquid film is saturated with gas at the interfacial concentration (CA,i); thus, the maximum rate of reaction is k2CB,bulkCA,iδL. It is an important parameter used in Chemical Reaction Engineering.

## What is the importance of Hatta number in gas liquid non catalytic reactions?

Generally, at increasing values of the Hatta number the chemical reaction is approaching the gas-liquid interface and the enhancement factor EA is limited by the value given by Einf. Depending on the absolute value of Hatta number and the ratio between Ha and Einf three absorption regimes can occur.

## What is film theory in mass transfer?

The film theory has been extensively applied to describe the mass transfer in systems in which fluid phases are present. The theory considers that the resistance to mass transfer in a given turbulent fluid phase is present in a thin layer adjacent to the interface that is called a film (Seader et al., 2011).

## How do you calculate effectiveness factor?

The effectiveness factor η has been defined as ‘the ratio of the real reaction rate of the catalyst particle to the imaginary reaction rate when the whole particle is assumed to bathe in the surface reactant concentration’ [6, 7].

## How do you solve effectiveness?

The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it’s energy production or machine efficiency.

## What is the enhancement factor?

The enhancement factor E in Eq. ( 10) is defined as the ratio of the liquid mass-transfer coefficients for absorption with and without a chemical reaction.

## How is IEF calculated?

IEF=MSE1/MSE2; fprintf(‘The Image Enhancement Factor is %. 2f’,IEF); Hope it helps!

## What is y * in mass transfer?

yA* is the concentration (mole fraction) in vapor phase that is in equilibrium with xAL. Driving force for mass transfer: ( yAG – yA* ) in the gas phase (as indicated by line PC) and ( xA* – xAL ) in the liquid phase (line PD).
