Transfer Coefficient. It can be shown in a relatively straightforward manner that in typical mass transfer problems the sherwood number depends on two important groups. X we define the sherwood number as.
P a displaystyle pa is a fictitious partial pressure in equilibrium with the concentration in the bulk fluidalthough the choice between writing the mass transfer coefficient in terms of the liquid side or the gas side is arbitrary the most common method is to write it in terms of the side with the most. Convective heat transfer coefficient h c w m 2 k temperature t s c temperature t a c results heat transfer w convective convection heat transfer calculator heat transfer area ft 2 convective heat transfer coefficient hc btu hr ft 2 f temperature ts f temperature ta f results heat transfer btuhr. As can be seen the constant of proportionality will be crucial in calculations and it is known as the convective heat transfer coefficient hthe convective heat transfer coefficient h can be defined as.
Sh k d cd x ab. Re and the other is the schmidt number. Overall heat transfer coefficient table charts and equation. Heat transfer coefficient is a quantitative characteristic of convective heat transfer between a fluid medium a fluid and the surface wall flowed over by the fluid.
