Pipe Sizing Method

Choose between three options for pipe sizing:

  1. Maximum Velocity: Ensures the pipe does not exceed a set maximum velocity.

  2. Maximum Pressure Drop: Ensures the pipe does not exceed a set maximum pressure drop.

  3. Maximum Velocity and Pressure Drop: Ensures the pipe does not exceed a set maximum on both velocity and pressure drop.

Pressure Loss Method

Select between:

  1. Based on all System Component’s Specific Pressure Loss: Calculates pressure loss based on all components, such as pipes, fittings, and valves, for accurate results.

  2. Percentage on Top of Pipe Lengths Only: Adds a set percentage (e.g., 10-20%) on top of the pipe lengths only, useful when fittings and valves are not fully modelled.
