Question

Check whether the following equations are dimensionally correct:P+½ p.v²=h.p​

Answer 1

Answer:

The Bernoulli's equation is given by p+21ρv2+hρg=k, 

where p = pressure, ρ = 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

Your Answer

B

Pressure gradient

C

Modulus of elasticity

Correct Answer

D

Thrust
