FAQs About Compressible Flow Calculators

When do I need to use a compressible flow calculator instead of an incompressible flow calculator?

Use a compressible flow calculator when the gas flow speed is high or when there are large changes in pressure, as the density will change significantly.

What is Mach number and why is it important in compressible flow?

The Mach number is the ratio of flow speed to the local speed of sound. It is important because it defines the flow regime and determines how compressible effects will affect the fluid flow.

Can I use this calculator for liquids, or only for gases?

This tool is designed for gases. Liquids have completely different behavior, and so you need a calculator specifically designed for liquids.

What are isentropic conditions?

Isentropic conditions refer to a flow where the process is both adiabatic (no heat transfer) and reversible (no friction or other losses).

Is this tool free?

Yes, our Compressible Flow Calculator is completely free to use.
