pL = Liquid density, kg/m3

Fp = Packing factor, m-1

^L = Viscosity of Liquid, mPa s

Y = Ratio, (density of water)/(density of liquid)

g = Gravitational constant, 9.81 m/s2

FIG. 5.20.3 Generalized correlation for the calculation of pressure drops in packed columns.

Using Figure 5.20.3, the engineer can then calculate the G value and hence the required column diameter.

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
