Question

If P is the pressure of a gas and p is its density,then find demension of velocity in terms of P and p

Answer 1

By definition of pressure = P = force / area from here

Force F = P * area = P * L ^ 2 (surface = squared length)

the length L = speed * time = V * t

F = P * L ^ 2 = P (Vt) ^ 2 = P * V ^ 2 * t ^ 2

may this help you...
