Question
Does the water coming out from the turbines move at the same speed as the water going into them?Explain your answer with reference to the energy transformation occurring in the turbines.
Solution
No, the water coming out from the turbines does not move at the same speed as the water going into them. Here's why:
-
Energy Transformation: The primary purpose of a turbine in a hydroelectric power plant is to convert the kinetic energy of moving water into mechanical energy, which is then converted into electrical energy by a generator.
-
Energy Transfer: When water enters the turbine, it has a high kinetic energy due to its speed and volume. As the water passes through and moves the turbine blades, its kinetic energy is transferred to the blades, causing them to move.
-
Energy Reduction: This transfer of energy from the water to the turbine reduces the water's kinetic energy, which means that the speed of the water exiting the turbine is less than the speed of the water entering the turbine.
-
Conservation of Energy: This is in line with the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. In this case, the kinetic energy of the water is converted into mechanical energy in the turbine and then into electrical energy in the generator.
So, in conclusion, due to the energy transformation occurring in the turbines, the water coming out from the turbines moves at a slower speed than the water going into them.

the turbine of a hydroelectric power station is built below the level of a lake. The water from the lake flows down a long pipe into an automatic gate. The gate controls the mass of water passing through the blades of the turbine per second.The passing water then rotates the turbine, which then rotates a group of magnets around a coil in an alternating current generator. The magnets rotate at a constant speed that generate an electromotive force (e.m.f) of 50 000 V across a coil.In Fig 10.2 below, the running water causes the turbine to turn anticlockwise. However, the electric current drawn from the generator produces a clockwise moment that opposes the rotation of the turbine.To generate the e.m.f. of 50 000 V, the running water would need to hit the turbine blades at a certain mass per second in order to overcome the opposing moment and to turn the turbine in the anticlockwise direction. at the end the water is discharged into a river at a constant speed of 10m/s. to generate 50000V, 20A is drawn from generator, moment required to turn the turbine is 34320Nm, mass of water hitting the blades per second is 339 kg/s. calculate the amount of energy gained by the generator when 339 kg of water flows through the turbine
