Indicated Thermal Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Indicated Thermal Efficiency = Brake Power/Heat Energy
IDE = BP/Q
This formula uses 3 Variables

Variables Used

Indicated Thermal Efficiency - Indicated Thermal Efficiency is given by the ratio of indicated power generated by the engine to the power generated by the combustion of the fuel.
Brake Power - (Measured in Watt) - Brake Power is the power obtained at the engine flywheel and is measured with the help of a dynamometer.
Heat Energy - (Measured in Joule) - Heat Energy is the amount of total heat required.

STEP 1: Convert Input(s) to Base Unit

Brake Power: 190 Kilowatt --> 190000 Watt (Check conversion here)
Heat Energy: 4200 Joule --> 4200 Joule No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

IDE = BP/Q --> 190000/4200

Evaluating ... ...

IDE = 45.2380952380952

STEP 3: Convert Result to Output's Unit

45.2380952380952 --> No Conversion Required

FINAL ANSWER

45.2380952380952 ≈ 45.2381 <-- Indicated Thermal Efficiency
