Question

Larger range of flow can be measured without pressure head being too ___________ in a viscous flow meter.

(a) small

(b) large

(c) deep

(d) none of the mentioned

I had been asked this question in an international level competition.

This interesting question is from Measurement and Testing topic in chapter Measurements and Testing/Performance Parameters and Characteristics of IC Engine

Answer 1

The correct answer is:

(b) large

In a viscous flow meter, a larger range of flow can be measured without the pressure head being too large. This is because the pressure drop in viscous flow meters is typically sensitive to flow rate, and excessively high pressure heads would lead to inaccuracies or damage to the system.
