Division Formula 8

United Kingdom

S_{η_{EI}} = \sqrt{\sum_{i = 1}^{4} {(h_{i} \times S \bar{η_{{EI}_{i}}})}^{2}}

The standard deviation of the alternator efficiency ( $S_{η_{EI}}$ ) leads to an error in the CO₂ savings ( $S_{C_{{CO}_{2}}}$ ). That error is calculated in accordance with formula 9:
