Friction Power of Diesel Engine Solution

Follow our step by step solution on how to calculate Friction Power of Diesel Engine?

FIRST Step Consider the formula

P f = P 4i - P 4b

Next Step Substitute values of Variables

∴

P f = 7553kW - 5537kW

Next Step Convert Units

∴

P f = 7.6E+6W - 5.5E+6W

Next Step Prepare to Evaluate

∴

P f = 7.6E+6 - 5.5E+6

Next Step Evaluate

∴

P f = 2016000W

LAST Step Convert to Output's Unit

∴

P f = 2016kW
