Question

Which of the following statements are true in relation to water hammer phenomenon?

Select the correct answer using the codes given below:

• A. 3 and 5
• B. 2 and 4
• C. 2 and 5
• D. 1, 2, 3 and 4

Answer 1

The correct option is B 2 and 4

Water hammer is a transient flow conditon and it is governed by Euler's model. The velocity of pressure wave.

$C=\sqrt{\frac{\frac{k}{\rho }}{1+\frac{Dk}{Et}}}$

Where E is the volume modulus of fluid
$E_p\text{is modulus of elasticity of pipe}$
d, t are diameter and thickness of pipe respectively
