Scientific Cooling Classes


Turbulent Flow Calculator

Find the flow rate where your cooling water makes the biggest impact on heat transfer. Enter your water temperature, percent of Ethylene Glycol, cooling circuit shape and size. The calculator will show you the flow rate needed to achieve your desired Reynolds Number.
Read the User Guidelines to find out how the Reynolds Number is calculated and how it applies to injection molding.
