**RAREFIED FLOW CALCULATOR**

Email: sharipov@fisica.ufpr.br

The applet calculates mass
flow rates through pipes and orifices over the whole range of the gas
rarefaction. Gas rarefaction and viscosity can be calculated also by Gas Dynamics Toolbox. If you notice problems with
calculations, please, let me know.

**Key words**: Rarefied gas, Knudsen number, gas rarefaction, flow rate,
throughput, pipe, tube, channel, orifice, Poiseuille
flow, thermal creep, thermolecular pressure
difference, vacuum, microfluidics
