    What is the significance of Lewis number?

    Levis no is used to characterise the fluid flow when both heat & mass transfer takes place simultaneously.

    Why baffles are used in reactors?

    By using baffles we increase the turbulence of fluid and thus heat transfer coefficient increases. It also use to hold the tubes.

    fouling factor

    How can we reduce the fouling factor?
  4. In counter flow the difference in temperature between hot fluid & cold is almost const. and so that heat transfer takes place longer but in case of parallel flow the difference in temperature continuously decreases so that transfer of heat decreases continuously.
