Silt-containing wastewater flowing at a rate of 24.2x103 m3/day was fed to a sedimentation tank with dimensions  L= 39 m, W= 8m, H=3m The SG of the particles is 2.68. What would be the smallest particle size (in µm) that can be removed from this operation? Assume flow is within Stokes region and that the particles are spherical. The density and viscosity of water is 1000 kg/m3 and 0.001 kg/m-s, respectively.

Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.
