Chapter 14, Problem 41R

To determine

To choose: The correct option.

Answer to Problem 41R

Option (A)

Explanation of Solution

Introduction:

Bernoulli’s equation describes the flow of the fluid between different locations. It states that the sum of kinetic energy, hydraulic energy and potential energy at point remain conserved.

The hose end sprayer is the fluid system in which the flow of water takes place according to Bernoulli’s principle. So, the option (A) is correct.

The skateboard is used for moving and it is based on the aerodynamic principle. So, the option (B) is incorrect.

The piston is the moving part of the engine, which is not based on Bernoulli’s principle. So, the option (C) is incorrect.

The snowboard is used to move on the ice. So, the option (D) is incorrect.

Conclusion:

Thus, the option (A) is correct.
