Question

The $SI$ unit of pressure gradient is

• A. $N{m}^{-2}$
• B. $Nm$
• C. $N{m}^{-1}$
• D. $N{m}^{-3}$

Answer 1

Answer: (D)

Pressure gradient $=\frac{\text{Pressure}}{\text{Distance}}$
$\because$ The $SI$ unit of pressure is $N{m}^{-2}$ and distance is $m$.
$\therefore$ The SI unit of pressure gradient is $N{m}^{-3}$.
