The Bernoulli's equation is given by `p+(1)/(2)rhov^(2)+hrhog=k`. Where `p=` pressure, `r=` 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 :

Options

A. Velocity gradient
B. Pressure gradient
C. Modulus of elasticity
D. Thrust

Answer

C

Explanation

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)]`
