## Baffles in heat exchangers

Baffles in heat exchangers are often used as a core element in any shell and tube heat exchanger design. This short article will discuss the use of baffles and some common guidelines on their usage in heat exchangers.

## How to calculate the Overall Heat Transfer Coefficient

How to calculate the Overall Heat Transfer Coefficient? Heat exchanger setup typically involves two flowing fluids separated by a solid wall. Heat is first transferred from the hot fluid to the wall by convection, the heat is then transferred through the wall by conduction, and lastly the heat is transferred […]

## What is a compact heat exchanger?

Definition Compact heat exchanger can be characterized by its high ‘area density’ this means that is has a high ratio of heat transfer surface to heat exchanger volume. So Compact heat exchange is characterized by high heat transfer surface-area to volume ratios and high heat transfer coefficients compared to other […]

Fanning friction factor The Fanning friction factor is defined as follows: ff = fd /4 Where; ff =Fanning friction factor fd =Darcy friction factor Darcy friction factor The Darcy friction factor is defined as follows: fd = 4 […]

## Hazen-Williams equation

Hazen-Williams equation is a popular approach for the calculation of head loss of liquid in piping systems. In this method, Hazen-Williams coefficient is introduced to the equation, the coefficient eliminates the need for using Reynolds number. The Hazen-Williams coefficient is mainly used to account for the pipe roughness or efficiency.
