If the required fall rate or slope angle of a self draining line is not known, use the tube and pipe angle calculator to help you determine the required angle. It is also known as the fall rate.
- Create a new self draining style or edit an existing self draining style. If you edit an existing self draining style, clear the value of the custom elbow in the fittings list to select the calculator.
- In the Tube and Pipe Styles dialog box, choose the calculator icon
to calculate the slope angle based on the amount the pipe segment drops vertically over a given horizontal distance. - In the calculator dialog box, enter the values for vertical drop and horizontal distance. Specify the round up or round down increment value.
Angle Read-only calculated value based on Drop and Distance input. Displays the angle between the vertical segment and the self draining segment.
Slope Read-only calculated value based on Drop and Distance input. Displays the angle between horizontal and the self draining segment.
Drop Vertical distance input for calculated slope angle.
Distance Horizontal distance input for calculated slope angle.
Increment The increment round-off or cut-off value by which the calculated angle is adjusted to satisfy the minimum and maximum constraints.
Round Up Select to enable the calculated slope angle value to round up to the closest value specified in the Increment area.
Round Down Select to enable the calculated slope angle value to round down to the closest value specified in the Increment area.
- A read-only calculated angle value is displayed in the Angle and Slope fields.
- When finished, click OK to accept the calculation and close the dialog box. Clicking OK enters the angle in the custom elbow angle box in the style. Click Close to discard the calculation and close the angle calculator dialog box.
