Brake specific fuel consumption Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Specific Fuel Consumption = Fuel Consumption in IC engine/Brake Power
BSFC = ṁ_f/BP
This formula uses 3 Variables

Variables Used

Brake Specific Fuel Consumption - (Measured in Kilogram per Second per Watt) - Brake Specific Fuel Consumption is the fuel consumption per unit time per unit brake power.
Fuel Consumption in IC engine - (Measured in Kilogram per Second) - Fuel Consumption in IC engine is the amount of fuel consumed by the engine.
Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.

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
Brake Power: 0.008 Kilowatt --> 8 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BSFC = ṁ_f/BP --> 0.0009/8

Evaluating ... ...

BSFC = 0.0001125

STEP 3: Convert Result to Output's Unit

0.0001125 Kilogram per Second per Watt -->0.405 Kilogram per Hour per Watt (Check conversion here)

FINAL ANSWER

0.405 Kilogram per Hour per Watt <-- Brake Specific Fuel Consumption

(Calculation completed in 00.004 seconds)
