Indicated Thermal Efficiency given Indicated Power Solution

Follow our step by step solution on how to calculate Indicated Thermal Efficiency given Indicated Power?

FIRST Step Consider the formula

IDE = (\frac{IP}{m f \cdot CV}) \cdot 100

Next Step Substitute values of Variables

∴

IDE = (\frac{0.9kW}{0.14kg/s \cdot 1600kJ/kg}) \cdot 100

Next Step Convert Units

∴

IDE = (\frac{900W}{0.14kg/s \cdot 1.6E+6J/kg}) \cdot 100

Next Step Prepare to Evaluate

∴

IDE = (\frac{900}{0.14 \cdot 1.6E+6}) \cdot 100

Next Step Evaluate

∴

IDE = 0.401785714285714

LAST Step Rounding Answer

∴

IDE = 0.4018
