Question

Water flows through a horizontal pipe. At one point, the velocity is $2~m/s$ and the pressure is $2~m$ of water column. What is the pressure at another point where the velocity is $3~m/s$?
(Density of water $=10^3~kg/m^3$)

• A. $1.75~m$ of water
• B. $1.2~m$ of water
• C. $1~m$ of water
• D. $1.5~m$ of water

Hint:

In a horizontal pipe: \[ \text{Higher velocity} \Rightarrow \text{Lower pressure} \] according to Bernoulli’s principle.

Answer 1

The Correct Option is D
