Variables Used
Dimensionless Parameter - Dimensionless Parameter is a numerical value without units used to express ratios, similarities, or relationships between physical quantities.
Hydraulic Radius - (Measured in Meter) - Hydraulic Radius is the ratio of the cross-sectional area of a channel or pipe in which a fluid is flowing to the wet perimeter of the conduit.
Inlet Impedance - Inlet Impedance is measure of opposition to airflow at an inlet, influences performance and efficiency of fluid systems.
Entrance Energy Loss Coefficient - Entrance Energy Loss Coefficient [dimensionless] The loss coefficient (ζ) is a dimensionless number (characteristic coefficient) to calculate the head loss.
Exit Energy Loss Coefficient - Exit Energy Loss Coefficient [dimensionless] is a dimensionless number (characteristic coefficient) to calculate the head loss.
Inlet Length - (Measured in Meter) - Inlet Length is the length of a narrow water passage between peninsulas or through a barrier island leading to a bay or lagoon.

What is Inlet flow patterns?

An Inlet has a "gorge" where flows converge before they expand again on the opposite side. Shoal (shallow) areas that extend bayward and oceanward from the gorge depend on inlet hydraulics, wave conditions, and general geomorphology. All these interact to determine flow patterns in and around the inlet and locations where flow channels occur.
