Gravity Sewer Design:

Velocity (V) - Arch Pipe
• Calculate the velocity (V) of gravity flow in an arch pipe.

Velocity (V) - Round Pipe
• Calculate the velocity (V) of gravity flow in a round pipe.
Flow (Q) - Arch Pipe
• Calculate the flow volume (Q) of gravity flow in an arch pipe.
Flow (Q) - Round Pipe
• Calculate the flow volume (Q) of gravity flow in a round pipe.
Diameter (D) - Round Pipe
• Calculate the diameter (D) for a flow volume (Q) of gravity flow in a round pipe.
Slope (S) - Arch Pipe
• Calculate the energy grade line slope (S) required to produce a flow volume (Q) in an arch pipe.
Slope (S) - Round Pipe
• Calculate the energy grade line slope (S) required to produce a flow volume (Q) in a round pipe.
Minor Losses
• Calculate the minor losses of a pipe under gravity flow conditions and pressure flow conditions.  Minor losses are used to check sewer system surcharge.
Storm Drain Inlets
• Calculations for the design of storm drain inlets. Solve calculations for curb inlets, slotted inlets and grade inlets under a variety of flow conditions.
• Calculate the load on rigid pipe from trench backfill over the pipe.
