PEW - the Process Engineers' Workbench

PEW saves design time and costs by bringing together a collection of important and frequently used chemical engineering calculations. There are calculations for fluid flow, heat transfer, mixing, and vessel calibration.

All the calculations have been verified and documented with extensive online help. The interface is presented in a standardised, easy-to-use format and the results can be displayed in tables and graphs. Features include unit conversion & calculators for physical properties, MW, friction factors, pipe diameter, and pipe roughness.
