| \( S = \Delta S \; C_p \; [ \; ln \; ( T_f \;/\; T_i ) \; ] \) | ||
| Symbol | English | Metric |
| \( S \) = Entropy | \(Btu \;/\; lbm-R\) | \(kJ \;/\; kg-K\) |
| \( \Delta S \) = Entropy Change | \(Btu \;/\; lbm-R\) | \(kJ \;/\; kg-K\) |
| \( C_p \) = Heat Capacity at Constant Pressure | \(Btu \;/\; R\) | \(kJ \;/\; K\) |
| \( ln \) = Natural Logarithm | \(dimensionless\) | \(dimensionless\) |
| \( T_f \) = Final Temperature | \(R\) | \(K\) |
| \( T_i \) = Initial Temperature | \(R\) | \(K\) |
