As gas flows through a pipe, how do the flow velocity and pressure change as the cross-sectional area of the pipe increases? Is there a formula?
As the cross-sectional area increases, the flow velocity decreases. According to the law of conservation of mass, q = v*S; therefore, the pressure will drop. The extent of this decrease may be negligible or it may be significant, and it is necessary to analyze it based on the specific conditions upstream and downstream
