According to Pascals law the pressure of gas in a vessel is_____________?
Correct answer: B. Same in all direction
- A. Different in different direction
- B. Same in all direction
- C. Same only along opposite directions
- D. Same only along normal directions
Explanation
Pascal's law states that pressure applied to an enclosed fluid is transmitted equally in all directions. Gas pressure therefore acts equally in every direction at a point when the gas is in equilibrium. The likely wrong choice is c, which confuses equal pressure in opposite directions with equality in all directions.

About Fluid Flow
Fluid flow covers pressure, density, viscosity and the motion of liquids and gases through pipes or open channels. It includes the continuity equation, Bernoulli equation, streamline and turbulent flow, and the effects of changing area, height and speed. Viscosity and ideal fluid assumptions must not be confused with pressure effects.
