The Bernoull's equation is given by
`P+(1)/(2)pv^(2)+hpg=k`
Where P=pressure, p=density, v=speed, h=height of the liquid column, g=acceleration due to gravity and k is constant. The dimensional formula for k is same as that for :

A

Velocity gradient

B

Pressure gradient

C

Modulus of elasticity

D

Thrust

Text Solution

Verified by Experts

The correct Answer is:
C

k is dimensionally equal to P
`k = [M^(1)L^(-1)T^(-2)]`
Modulus of elasticity = `("Stress")/("Strain") = ("F/A")/((Delta l )/(l)) = [ML^(-1)T^(-2)]`
