Energy Consumption at Axle of Train Solution

Follow our step by step solution on how to calculate Energy Consumption at Axle of Train?

FIRST Step Consider the formula

E A = 0.01072 \cdot (\frac{{V m}^{2}}{D}) \cdot (\frac{W e}{W}) + 0.2778 \cdot R sp \cdot (\frac{d 1}{D})

Next Step Substitute values of Variables

∴

E A = 0.01072 \cdot (\frac{{98.35km/h}^{2}}{258km}) \cdot (\frac{33000AT (US)}{30000AT (US)}) + 0.2778 \cdot 9.2 \cdot (\frac{0.125m}{258km})

Next Step Convert Units

∴

E A = 0.01072 \cdot (\frac{{27.3194m/s}^{2}}{258000m}) \cdot (\frac{962.5001kg}{875.0001kg}) + 0.2778 \cdot 9.2 \cdot (\frac{0.125m}{258000m})

Next Step Prepare to Evaluate

∴

E A = 0.01072 \cdot (\frac{{27.3194}^{2}}{258000}) \cdot (\frac{962.5001}{875.0001}) + 0.2778 \cdot 9.2 \cdot (\frac{0.125}{258000})

Next Step Evaluate

∴

E A = 3.53505942315053E-05J

Next Step Convert to Output's Unit

∴

E A = 9.81960950875147E-09W*h

LAST Step Rounding Answer

∴

E A = 9.8E-9W*h
