Question

When a liquid is flowing through a tube or variable diameter, the pressure is?

• A. Maximum where the velocity is maximum
• B. Maximum where the velocity is minimum
• C. Minimum where the velocity is minimum
• D. None of the above is correct

Answer 1

The correct option is B Maximum where the velocity is minimum

From the principle of continuity $A_1{v}_1=A_2{v}_2$ and bernoulli's theorem $P+\rho gh+\frac{1}{2}\rho v^2$ w can conclude that pressure is maximum when the velocity is minimum.
