The velocity of kerosene oil in a horizontal pipe is 5 m/s. If g = 10m/s then the height head of oil will be:
Correct answer: A. 1.25 m
- A. 1.25 m
- B. 12.5 m
- C. 0.125 m
- D. 125 m
Explanation
The velocity head of a fluid is calculated using the formula: velocity head = v² / (2g), where v is the velocity of the fluid and g is the acceleration due to gravity. In this question, the velocity of kerosene oil is given as 5 m/s and g is 10 m/s². Substituting these values into the formula gives: (5)² / (2*10) = 25 / 20 = 1.25 m. Therefore, the correct answer is 1.25 m. Options B, C, and D result from incorrect calculations or misunderstandings of the formula.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
