Water contains two basic forms of energy: potential and kinetic. Potential energy pertains to stored energy, while kinetic energy is the energy of motion. Hydroelectric plants are generally constructed by using dams to store water in reservoirs. Once water is released, its potential energy is converted into kinetic energy.
The turbines in hydroelectric facilities are positioned in such a way that the rapidly flowing water directly passes through them. The tremendous mechanical force that the running water exerts on the blades triggers the power generators, which are secured to the turbines. These machines then transform the mechanical energy into electricity

(Solved)
Into a stream, with no trace of salt initially, a salt with a concentration of 20 mg/cc is introduced at a constant rate of 2 litres per minute. The samples collected at a downstream section sufficiently far away indicated an equilibrium salt concentration of 0.05 ppm. Determine the discharge in the stream from this data.

(Solved)
The following data pertain to streamflow in a river at a given gauge station. The rate of rise in water surface elevation = 10.0 cm/h. the normal discharge for the river stage obtained from the steady flow rating curve = 150 m3/s. slope of the river bed = 3 x 10-4. Assume the velocity of the flood wave to be 2.5 cm/sec, compute the river discharge.

(Solved)
A drainage basin has an area of 210 km2. The average depth of rainfall received by it during a monsoon period is computed as 65 cm, while the runoff measured at its outlet during the same period is estimated to be 5.68 x 107 m3. Compute the depth of runoff. What percentage of rainfall has become runoff? If all this runoff volume is stored and used to irrigate a crop which requires 60 cm of water, how many hectares can be irrigated?

(Solved)
The mean daily flows at a gauging station for a period of 7 days are 7, 27, 58, 41, 31, 20 and 13 m3/s respectively. What is the total volume of streamflow at the site in cumec-days(metres cubed per second.)? and in hectare-metres? What is the mean flow rate for the week? If the drainage area at the site is 100 km2, what is the runoff volume in cm?
