Changes in the flow velocity of gas within the system when system pressure decreases
Thread Content
Dear sea friends, I would like to ask everyone: when the system pressure decreases, how does the flow rate of the gas inside the system change? Can it be explained using Bernoulli’s equation from chemical engineering principles?
The question wasn’t expressed clearly; please provide more details.
Personally, I think it’s not possible, because gas is compressible
The Bernoulli equation is applicable to incompressible fluids; gases, on the other hand, are compressible. Generally, as the system pressure decreases, the driving force weakens due to the constant resistance in the system, so the flow velocity should decrease
No need for Bernoulli’s equation. It is a material balance problem. In production, with a constant amount of raw material, changes in system pressure have no effect on the mass flow rate of the gaseous material.
