Fan calculation
Thread Content
After the exhaust gas is drawn out using a fan and sent to a device located 30 meters high, is the wind pressure calculated as the pipeline resistance loss plus the static pressure corresponding to a height of 30 meters? Please advise on how to design it specifically
The static pressure in the gas phase can basically be ignored; even if it is taken into account, its value is very small
It would be better to ask the supplier directly, or find the fan’s data sheet
To calculate wind pressure, I think height needs to be taken into account, as the wind pressure generated by fans is not very high to begin with. Consider the air volume. Select the fan based on wind pressure and air volume.
The principle is the white-effort equation; pay attention to the pressures at the inlet and outlet – the pressure drop in the pipes needs to be calculated carefully
It is mainly the pipeline pressure drop, which is calculated using Bernoulli’s equation.
You just need to calculate the resistance of the inlet and outlet pipelines; with a pipeline layout diagram, it’s possible to do this calculation. Generally, height is not taken into consideration
