What is ht?

ht is open-source software for engineers and technicians working in the fields of chemical or mechanical engineering. It includes modules for various heat transfer functions.

The ht library depends on the SciPy library to provide numerical constants, interpolation, integration, and numerical solving functionality. ht runs on all operating systems which support Python, is quick to install, and is free of charge. ht is designed to be easy to use while still providing powerful functionality. If you need to perform some heat transfer calculations, give ht a try.
