Turbulente stroming - Probleemaanpak

Consider a liquid that needs to be carbonated. Both the liquid and the carbon dioxide gas are cooled. The temperature is selected as 20 degrees Celsius to enhance carbon dioxide dissolution.

The carbon dioxide gas is pressurized to approximately 550 kPa to ensure sufficient carbonation.

Carbon dioxide is pumped at a steady flow rate through a pipe connecting two tanks.

Due to the high Reynolds number, which is greater than 4000, the flow of carbon dioxide is turbulent.

The carbon dioxide flow rate depends on the cross-sectional area of the pipe and the velocity of flow.

This velocity of flow is used in the Reynolds number equation, set equal to 5000, to derive a formula for the pipe diameter.

To find the pipe diameter, the dynamic viscosity of carbon dioxide at 20 degrees Celsius is obtained from the physical properties table.

Substituting these values into the equation provides the diameter of the pipe needed to achieve the desired flow conditions.
