The energy ratio (ER) equation you provided, ER = Pt/Pc, relates the total energy output (Pt) to the energy input associated with flow losses in a complete circuit (Pc).
- ER is the energy ratio, a dimensionless quantity that represents the ratio of output energy to input energy. It provides a measure of the efficiency or effectiveness of a system or process.
- Pt is the total energy output, which is the energy obtained or produced by the system.
- Pc is the energy input associated with flow losses in the complete circuit. It refers to the energy consumed or lost due to friction, turbulence, or other factors that affect the flow within the circuit.
