Fuel conversion efficiency Solution

Follow our step by step solution on how to calculate Fuel conversion efficiency?

FIRST Step Consider the formula

η f = \frac{W}{m f \cdot Q HV}

Next Step Substitute values of Variables

∴

η f = \frac{100KJ}{0.005 \cdot 50000kJ/kg}

Next Step Convert Units

∴

η f = \frac{100000J}{0.005 \cdot 5E+7J/kg}

Next Step Prepare to Evaluate

∴

η f = \frac{100000}{0.005 \cdot 5E+7}

LAST Step Evaluate

∴

η f = 0.4
