Total head loss is used in some equations. It is simply the sum of major and minor losses, and is denoted as h.l.
Head loss is also calculated independent of the velocity head. This is used in the [ | ] program. Include Page AGUACLARA:C.p AGUACLARA:C.p
The total head loss in the manifold is used in the Exit Channel, Launder, and Sludge Drain program.

Orifice Equations
Orifice equations are used in the Entrance Tank, Exit Channel, Flow Control Module, and Launder. These equations include simple calculations for the area of a circle (A.circle) and the diameter of a circle (D.circle) given an area.
The flow rate through the orifice is calculated using a Pi value found in the Design Assumptions.
