Energy Flow Diagram (Sankey Diagram)
Q. What is energy flow diagram ? State its significance from energy audit point of view.
- In such diagrams the flow is shown from input to output and in between these two different losses are indicated, so that Input-Losses-Output.
- Energy input cannot be utilized fully and the lost energy is studied and ways and means can be provided to minimize the losses.
- In this section, we take three cases :
- Energy flow diagram in a plant or in a system.
- Energy flow converting electrical energy-heat light.
- Energy flow diagram (electrical to mechanical conversion taking the case of water pumping unit).
- Energy flow diagram of induction motor.
