Gas Flow

Dear Sir,

I have Flue gas flow through a 24" pipe is around 10000Nm³/hr with suction of negative -2mmWC.If I change the pipe dia by 18" keeping suction negative -2mmWC as it is ,then what is a flow through it.

Regards

It will be according to the Darcy-Weisbach equation.

If the pipe is long and straight, so all the loss is due to friction, flow for a given ΔP varies as 5th power of diameter. If it's mostly local losses, bends, valves etc, it's the 4th power.
