Question

In which of the following measuring devices is Bernoulli's equation NOT used?

• A. Pitot tube
• B. Orifice meter
• C. Viscometer
• D. Venturimeter

Answer 1

Answer:

C. Viscometer

Bernoulli's equation states that the total energy per unit volume remains constant for a streamlined flow of an ideal liquid in a varying cross-section tube. Hence, all measuring devices like

1. Pitot tube,

2. Venturimeter,

3. and Orifice meter work on it.

But Viscometer does not use Bernoulli's equation. Venturimeter and Orifice meter are cost and performance efficient devices that work on Bernoulli's equatio
