Question

What is the dimensional formula of pressure difference..

Answer 1

It would be same as pressure....i.e., M L^-1 T^-2.......

Answer 2

The dimensional formula of pressure difference is $\Delta P=\left[M L^{-1} T^{-2}\right]$

Explanation:

The dimensional formula is calculated based on the fundamental units known for the basic 7 fundamental quantities.

Hence, for the dimensions of Pressure difference will be, derived from its formula where pressure is net force unit per area.

The pressure difference will follow same formula, thereby,

$\Delta P=\left (\frac{\Delta F}{\Delta A} \right)$

$\Delta P=\frac{\left[M L T^{-2}\right]}{\left[L^{2}\right]}$

$\Delta P=\left[M L^{-1} T^{-2}\right]$
