How would you explain the effect of the water’s head flow in terms of energy transformations?
In general, the greater the water flow and the higher the head, the more electricity a hydropower plant can produce. At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity.
What is meant by energy transformation?
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. … For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home’s air to raise its temperature.
What is the process of energy transformation?
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
What is the best definition for energy transformation?
Energy transformation or energy conversion is the process of changing one form of energy to another. … Energy in its various forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, light, or performing mechanical work to operate machines.
What is the effect of the water’s head of flow to the rotation of the blades?
The water flow generates pressure between the front and back of the blades, develops a reverse reaction force on the runner, and thus, forms rotation torque to rotate the runner.
What is the energy transformation in hydroelectric energy?
“A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
What is transformation of energy explain with any two suitable examples?
Examples: The electrical energy in an electric bulb is converted into heat and light energy. The electrical energy in an electromagnet is converted into magnetic energy. A cell or a battery converts chemical energy into electrical energy.
How do we use transformation of energy in our daily life?
- A toaster transforms electrical energy into thermal energy.
- A blender transforms electrical energy into mechanical energy.
- The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.
What is the need of transformation of energy?
The need and necessity of transformation of energy is very crucial. The energy transformation makes the process to conduct. Any process like power on, vehicle driving, chemical reactions requires the energy transformation. The energy can be defined as mechanical, chemical and light energy.
What do you understand by transformation of energy Class 9?
The change of one form of energy into another form of energy is called transformation of energy. For Ex:1)When a body is released from a height then potential energy is transferred into kinetic energy.
What energy transformation occurs when you rub your hands together?
When you rub your hands together, there is skin friction, converting the kinetic energy when you rub your hands to heat energy which is transformed to your hands, keeping them warm. Potential energy to mechanical energy to heat energy, potential stored in your muscle to move your hands.
How does energy transformation occurs in a ceiling fan?
(The fan’s blades move air around the room. The kinetic energy of the moving blades does work in moving air through the fan blades.) … The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.)
