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 press another point where the velocity is 3 m/s? (Density of water = 10³ kg/m³)

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

Hint:

Key Exam Tip:
Bernoulli's principle for horizontal flow is $h_1 + v_1^2/(2g) = h_2 + v_2^2/(2g)$. Always check units and use consistent values for constants like $g$.

Answer 1

The Correct Option is B
