This formula uses 4 Variables
Variables Used
Work done per cycle in ic engine - (Measured in Joule) - Work done per cycle in ic engine is defined as work done to push the piston downwards during the power stroke of the otto cycle in ic engine.
Indicated engine power - (Measured in Watt) - Indicated engine power is defined as the power that is produced in the cylinder of an engine as a result of the combustion of fuel.
Crankshaft revolutions per power stroke - Crankshaft revolutions per power stroke is defined as the number of crankshaft rotations when the ic engine takes one complete cycle.
Engine Speed in rpm - Engine Speed in rpm is the speed at which the crankshaft of the engine rotates.
STEP 1: Convert Input(s) to Base Unit
Indicated engine power: 100 Kilowatt --> 100000 Watt (Check conversion here)
Crankshaft revolutions per power stroke: 2 --> No Conversion Required
Engine Speed in rpm: 500 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
W = (P*nR)/N --> (100000*2)/500
Evaluating ... ...
W = 400
STEP 3: Convert Result to Output's Unit
400 Joule -->0.4 Kilojoule (Check conversion here)
FINAL ANSWER
0.4 Kilojoule <-- Work done per cycle in ic engine
