bullet

Energy loss - heat loss in the thermodynamics screen

bullet

Pressure drop - pressure drop in the hydrodynamics screen

bullet

Spray effectiveness - coating efficiency in the process efficiency screen

bullet

Spray distribution effectiveness - bypass factor in the coating uniformity screen

Formulation

bullet

Tablet design optimization - see the marketing image change example

bullet

Tablet shape factor calculation - see the marketing image change example

bullet

Weight gain calculation based on film thickness - see the marketing image change example

Development and Scale Up

bullet

Batch size calculation is done in the process efficiency screen.  The scale up and marketing image change examples show the use of fill volume in determining the batch size.

Safety

bullet

Lower explosion limit calculation is done in the thermodynamics screen.  An example of using LEL in process design is provided in solvent mixture optimization.

Utilities

bullet

The thermodynamics and hydrodynamics screens provide calculations that can be used to assess utilities requirement
bullet

Moisture rate in the inlet air -- steam and chiller fluid requirements for humidification system

bullet

Process air flow rate -- heating and cooling load requirements

bullet

Pressure drop -- fan rating requirement
