Inlet Velocity with Turbulent or Laminar Flow
Inlet Velocity with Turbulent or Laminar Flow
(OP)
Hi,
When it comes to determine the suitable inlet velocity most designers / engineers has their own general rule of thumb per say for vapor flow somewhere around 10 m/s to 20 m/s and liquid flow somewhere around 3 m/s to 5 m/s.
My question is does type of flow can be a 'rule' for determining the appropriate inlet velocity and this is where I think the logic comes in mind that the appropriate inlet velocity shall be limit to laminar flow instead of turbulent flow but again this is my take on determining the inlet velocity.
Does anyone think the same as this logic? Also kindly share your general rule of thumb for determining the appropriate inlet velocity.

Laminar flow is very low for most "normal" fluids unless you're got really viscous fluids.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Inlet velocity through a heat exchanger.

The reason I was thinking of having laminar flow perhaps that turbulent flow 'may' contribute to uneven flow distribution between the plates.
