Questions and Answers

What is the significance of understanding laminar and turbulent streamflow in engineering and fluid mechanics?

It impacts how mass and heat are transferred. (correct)

It determines the speed of the boat.

It affects the color of the water.

It influences the noise level of the stream.

How do flow meters determine heat and mass transfer in fluid?

By analyzing the color of the water.

By measuring the height of waves.

By counting the number of fish in the stream.

By measuring the speed, pressure, and temperature of the fluid. (correct)

Why do thermal flow meters work best when streamflow is laminar?

To reduce noise created by turbulent flow.

Due to the color contrast created by laminar flow.

To enhance the taste of the water.

Because they are based on the bypass principle. (correct)
