Calculate scuba transfer whip pressures for various configurations

Scuba transfer whip pressure calculator

A small helper program for calculating pressures achieved when using a transfer whip between scuba tanks, especially useful for source/destination twinsets with manifold that can be closed.

By default Van Der Waals equations are used for calculating amount of gas. Use -use-ideal-gas parameter to use ideal gas equation instead.

Installation

There are no external requirements or dependencies.

Use go build . to build; then ./scuba-whip-calculator-go -h to see instructions.
