Hydraulic Diameter

Can anyone help me out how to find out Hydraulic diameter for the flow over a building.

Hydraulic diameter is typically used for internal flow. The flow over a building is an external flow. I do not think that hydraulic diameter is appropriate for this flow.

Is there a specific reason you need to calculate the hydraulic diameter for this problem?

Hi Lucky tran,

Thanks for sharing your knowledge.

There is no other specific reason for calculating hydraulic diameter.
