Fans and blowers provide air for ventilation and industrial process requirements. Fans generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other components in a fan system. The fan rotor receives energy from a rotating shaft and transmits it to the air.

Fans: Primary air moving devices used in industrial applications
Basic groups of fans are:

• Axial fans
• Centrifugal fans

The total work a fan must do to move a specified volume of air against the static pressure plus the velocity pressure is defined as total pressure of the system.

In this video we calculate duct friction loss with excel sheet and we applied the calculation on a duct work example. we estimated the external static pressure (ESP) for a fan coil unit (FCU).

Fan static head (ESP)

Static pressure:

Static pressure or static head is the potential energy put into the system by the fan. It is given up to friction in the ducts and at the duct inlet as it is converted to velocity pressure. At the inlet to the duct, the static pressure produces an area of low pressure.

Velocity pressure:

Velocity pressure is the pressure along the line of the flow that results from the air flowing through the duct. The velocity pressure is used to calculate air velocity.

Total pressure:

Total pressure is the sum of the static and velocity pressure. Velocity pressure and static pressure can change as the air flows though different size ducts accelerating and de-accelerating the velocity.
