Mechanical Engineering > GATE 2026 > Compressible Flow
An ideal gas passes isothermally through a long horizontal uniform cross-section pipe under steady flow. Consider that the pressure gradient in the pipe is sufficient for a finite change in the density of the gas. If the flow of the gas is purely pressure driven and subsonic throughout, then the average flow velocity
A
increases along the flow
B
decreases along the flow
C
does not change throughout the pipe
D
increases in the hydrodynamic entrance region and then decreases thereafter

Correct : a
