About This Product
In a curved tube, centrifugal force acts unequally on fluid moving at different speeds and sets up a secondary circulation. That secondary flow improves heat transfer, which is why helical coils serve for heating or cooling in process tanks, and it also steadies laminar flow so the change to turbulence comes at a higher critical Reynolds number. The Flow Through Helical Coil can be dispatched from India to Afghanistan, Barbados, Samoa, Serbia, Angola and Suriname.
Frequently Asked Questions
Which experiments can be done?
Comparing the pressure drop in the helical coil with that in a straight pipe of the same length, inside diameter and surface roughness; finding the critical Reynolds number for flow through the coil; and finding the friction factor for water in the coil.
Why is the critical Reynolds number higher in a coil?
Secondary flow caused by centrifugal force in the curved tube stabilises laminar flow, so the transition from laminar to turbulent flow takes place at a higher critical Reynolds number.
