Dimension of pressure is__________________?
Correct answer: C. ML-1T-2
- A. MLT
- B. ML-1T-1
- C. ML-1T-2
- D. ML-2T-2
Explanation
Pressure is force per unit area, so its dimensions are [P] = [F]/[A] = (MLT^-2)/L^2 = ML^-1T^-2. The common mistake is option b, which has T^-1 and corresponds to a quantity such as dynamic viscosity rather than pressure.

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.
