Water at 200c flows through a pipe of 10 mm diameter pipe at 1 m/s. is the flow turbulent ? a. yes b. no

Yes, the flow is turbulent.

Explanation:

Reynolds number gives the nature of flow. If he Reynolds number is less than 2000 then the flow is laminar else turbulent.

Given:

Diameter of pipe is 10mm.

Velocity of the pipe is 1m/s.

Temperature of water is 200°C.

The kinematic viscosity at temperature 200°C is m2/s.

Calculation:

Step1

Expression for Reynolds number is given as follows:

Here, v is velocity, is kinematic viscosity, d is diameter and Re is Reynolds number.

Substitute the values in the above equation as follows:

Re=64226.07579

Thus, the Reynolds number is 64226.07579. This is greater than 2000.

Hence, the given flow is turbulent flow.

can you make it more obvious. i can't see it properly
