Design Calculations

Tray Hydraulics

The hydraulic performance of a sieve tray for a given layout may be calculated using the methods presented in 'Distillation/Tray Columns: Performance'.

Tray Efficiency

Tray efficiency is a strong function of the physical properties of the vapour and liquid streams. It is also affected, to a lesser extent, by the flow rates and tray layout. In the latter case, only hole diameter, hole area and weir height have a small influence on the tray efficiency. The optimum design, which gives the maximum number of equilibrium stages in a column, is often obtained at minimum tray spacing and minimum number of flow paths that satisfy the hydraulic design criteria.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
