- Boiler Efficiency (η): η = (Heat Output / Heat Input) x 100%
- Steam Quality (x): x = (Mass of Dry Steam / Total Mass of Mixture)
- Specific Volume of Steam (v<sub>g</sub>): Obtained from steam tables based on pressure and temperature.
- Feedwater Pump Horsepower: HP = (GPM x Head in feet x Specific Gravity) / (3960 x Pump Efficiency)
- Heat Transfer Rate (Q): Q = U x A x ΔT, where U is the overall heat transfer coefficient, A is the heat transfer area, and ΔT is the temperature difference.
- Ohms Law: V = IR (Voltage = Current x Resistance)
