Here, Hw is the weir height in metres, p is the pitch of the holes in the sieve plate in metres, FP = (uj/ug)^(pi/pg) is the flow parameter, b is the weir length per unit bubbling area in metres_1.

The discharge coefficient, CD in eqn [4] is a function of the flow conditions near a hole. It is in fact dependent on the liquid present on the tray. It is correlated by:

All of the quantities appearing on the right-hand side have been defined previously.

Pressure Drop Calculation in the Liquid Phase

The liquid is transported down through the down-comer. The capacity of the downcomer should be sufficient to handle the liquid load without becoming the rate limiting factor, i.e. without the liquid backing up the downcomer to a significant extent. Figure 1B shows the pressure differential components making up the total head differential on the liquid side as the liquid backs up the downcomer to a height of hdc. The extent of liquid back-up can be estimated from:

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.
