Question

The Chimney works best on the principle of

• A. Speed Equation
• B. Light Equation
• C. Bernoulli's Equation
• D. The Equation Of Continuity

Answer 1

The correct option is C

Bernoulli's Equation

Explanation for the correct option:

Option C:

1. Chimneys involve a flow of fluid.
2. Among the given equations, Bernoulli's equation is the best suited for the study of the flow of fluid due to pressure variation.
3. Bernoulli's equations state that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.

Explanation for the incorrect option:

Option A:

1. The speed equation is given by the ratio of the distance traveled and the time.
2. This does not explain the flow of air in a chimney.
3. Hence, this is not the correct option.

Option B:

1. The light equation gives us the speed of light.
2. This does not explain the flow of air in a chimney.
3. Hence, this is not the correct option.

Option D:

1. The equation of continuity gives the relationship between the area and the velocity of a flow.
2. This does not explain the flow of air in a chimney.
3. Hence, this is not the correct option.

Hence, option C is the correct option.
