PEL 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:
- Fluid Flow
- Incompressible flow
- Compressible flow
- Gravity flow
- Manifold T-junctions
- Symmetrical T-junctions
- Expansions/contractions
- Orifice plates
- Restrictors
- Two phase flow
- Equipment
- Vessel Calibration
- Heat transfer
- Heat loss from pipes
- Heat loss from vessels
- Simple heat exchanger
- Tank solar heating
- Batch heating / cooling
- Heat transfer coefficients
- Finned tube coefficients
- Mixing
- Vortex profile
- Power Numbers
- Speed / Power curves
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.
