A 600-hectare farmland receives annual rainfall of 2500 mm. There is a river flowing through the farmland with an inflow rate of 5 m/s and an outflow rate of 4 m'/s. The annual water storage in the farmland increases by 2.5 x 10° m. Based on the hydrologic budget equation, determine the annual evaporation amount (in mm). [Note: 1 hectare = 10,000 m²]

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.
