ma = (maf*nR)/N
This formula uses 4 Variables
Variables Used
Mass of air at intake - (Measured in Kilogram) - Mass of air at intake is defined as the mass of the air that is drawn into the cylinder during intake stroke.
Air Mass Flow Rate - (Measured in Kilogram per Second) - Air mass flow rate is the mass of intake air that is flowing per unit time.
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
Air Mass Flow Rate: 0.9 Kilogram per Second --> 0.9 Kilogram per Second No Conversion Required
