Indicated specific fuel consumption Solution

STEP 0: Pre-Calculation Summary

Formula Used

Indicated Specific Fuel Consumption = Fuel Consumption in IC engine/Indicated Power
ISFC = ṁ_f/IP
This formula uses 3 Variables

Variables Used

Indicated Specific Fuel Consumption - (Measured in Kilogram per Second per Watt) - Indicated Specific Fuel Consumption is the fuel consumption per unit time per unit indicated power.
Fuel Consumption in IC engine - (Measured in Kilogram per Second) - Fuel Consumption in IC engine is the amount of fuel consumed by the internal combustion engine.
Indicated Power - (Measured in Watt) - Indicated Power is the total power produced due to combustion of fuel within the IC engine's cylinder in one complete cycle neglecting any losses.

STEP 1: Convert Input(s) to Base Unit

Fuel Consumption in IC engine: 0.0009 Kilogram per Second --> 0.0009 Kilogram per Second No Conversion Required
Indicated Power: 0.9 Kilowatt --> 900 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ISFC = ṁ_f/IP --> 0.0009/900

Evaluating ... ...

ISFC = 1E-06

STEP 3: Convert Result to Output's Unit

1E-06 Kilogram per Second per Watt -->0.0036 Kilogram per Hour per Watt (Check conversion here)

FINAL ANSWER

0.0036 Kilogram per Hour per Watt <-- Indicated Specific Fuel Consumption

(Calculation completed in 00.004 seconds)
