Question

What is the standard unit or SI unit of pressure gradient?

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

Answer 1

Answer: (D)

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