The balance between these two major contributions may be achieved for particles in the 7-15 |jm range with a reasonable development length (3-15 cm).

Figure 11 Different contributions to the apparent HETP versus development length. Curves 1, 2 and 3 correspond to particle size 5 |im. Curves 4-7 correspond to particle size 20 |im. Curves 1 and 4, total plate height. Curves 2 and 5 show the contribution of molecular diffusion. Curves 3 and 6 show the packing contribution, while curve 7 shows the mass transfer contribution (this last contribution is too small to be represented when dp = 5 |im). Dm = 1 x 10~5cm2s~1.

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.
