Question

The reading of differential manometer of a Venturimeter, placed at 45\(^\circ\) to the horizontal is 14 cm. If the Venturimeter is turned to horizontal position, the manometer reading will be

• A. Zero m
• B. \( \frac{14}{\sqrt{2}} \) cm
• C. \( \frac{14}{2} \) cm
• D. 14 cm

Hint:

In manometer-based fluid flow measurement, always ensure the setup is stable, as changing the angle might not alter the reading.

Answer 1

The Correct Option is D

When the differential manometer is turned from an inclined position to the horizontal position, the reading remains the same at 14 cm. This is because the vertical height change does not affect the reading in this case.
