Question

define pressure density &its dimensional formula​

Answer 1

Answer:

Density is the mass per unit volume of a substance or object, defined as ρ=m/V. ... Pressure due to the weight of a liquid of constant density is given by p=ρgh p = ρ g h , where p is the pressure, h is the depth of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity.

Explanation:

Pressure (P) = Force × Area-1. Or, P = [M1 L1 T-2] × [L2]-1 = M1 L-1 T -2. Therefore, the pressure is dimensionally represented as M1 L-1 T -2.

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
