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 internal combustion 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: 0.55 Kilowatt --> 550 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BSFC = ṁ_f/BP --> 0.0009/550

Evaluating ... ...

BSFC = 1.63636363636364E-06

STEP 3: Convert Result to Output's Unit

1.63636363636364E-06 Kilogram per Second per Watt -->0.00589090909090909 Kilogram per Hour per Watt (Check conversion here)

FINAL ANSWER

0.00589090909090909 ≈ 0.005891 Kilogram per Hour per Watt <-- Brake Specific Fuel Consumption

(Calculation completed in 00.009 seconds)

Brake Specific Fuel Consumption = Fuel Consumption in IC engine/Brake Power
BSFC = ṁ_f/BP

What is Brake Specific Fuel Consumption?

Brake Specific Fuel Consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft, power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power (here, brake power) produced.

How to Calculate Brake specific fuel consumption?

Brake specific fuel consumption calculator uses Brake Specific Fuel Consumption = Fuel Consumption in IC engine/Brake Power to calculate the Brake Specific Fuel Consumption, The Brake Specific Fuel Consumption formula is defined as the fuel consumption per unit time divided by the brake power of an IC engine. Brake Specific Fuel Consumption is denoted by BSFC symbol.
