A program to allow the very fast modeling of fluid flow, and the visualization of the streamlines and pressure distribution. Rectangular and circular sections can be entered as well as aerofoils. Example files are included, and many editing tools are provided. A flow rate and pressure gauge is also available.

Freeware. 397 units in 46 categories. Has all basic categories and engineering specific categories like enthalpy, heat capacity, heat transfer coefficient, moment of inertia, surface tension, torque and viscosity. Converts feet and inches to and from decimal lengths. Converts between dynamic and kinematic viscosity. Steel hardness equivalents. Gas Constant in 900 sets of units. Excludes archaic units. Powerful formatting and clipboard features.

Orifice calculates size, flowrate or pressure drops for gas and liquid orifice meters based on ANSI/API-2530-1991, Part 3 (AGA-3) or the International Standard ISO-5167-1:1991.
The program includes:
- Gas Orifices: Natural Gas, Air and Nitrogen;
- Liquid Orifices: Oil, Water, Methanol, MEG, DEG and TEG;
- Restriction Gas Orifices;
- Restriction Liquid Orifices
