Calculating Blower Power Requirements

Calculating Blower Power Requirements

Calculating Blower Power Requirements

(OP)
Could someone let me know the equations that can be used to calculate,


the temperature rise in a high-speed turbo blower if;

1. Inlet pressure and temperature
2. Outlet pressure

are known.



the power requirement for a high-speed turbo blower if;

1. air mass flow rate
2. inlet and discharge pressures

are known.


Thanks in advance.

RE: Calculating Blower Power Requirements

Do a search for fan affinity laws.

The power required to compress a given volume of air in a given time period is the same for any fan, blower or compressor working with air, ideal gases etc...

Power to heat air is just a function of the specific heat capacity of the air, the volume and the change in temperature.

Simples!!!
