Example A rectangular sedimentation tank with W=25m, L=50m and h=3m. The flow rate = 1500 m/h, and the influent particles concentration = following table shows the percentage of particles as a function of his diameter: 2000mg/l. The Volume of particle (mm) 0.001 10 0.005 20 0.01 15 0.015 15 0.02 20 0.025 20 Find: 1) Settling velocity, if particles density = 2650 kg/ m' and viscosity of water = 1.002*10°N.s/m? 2) Percentage removal for each particle and total percentage removal 3) Sludge depth, if the tank is cleaned one time per month. If percentage of solide = 8% and sludge density = 1150 kg/ m

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.
