Thrust power specific fuel consumption Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thrust Power Specific Fuel Consumption = Fuel Flow Rate/Thrust Power
TPSFC = m_f/T_P
This formula uses 3 Variables

Variables Used

Thrust Power Specific Fuel Consumption - (Measured in Kilogram per Second per Watt) - Thrust power specific fuel consumption is the measures of the overall thermal efficiency of an engine for a given air speed and jet speed.
Fuel Flow Rate - (Measured in Kilogram per Second) - Fuel Flow Rate refers to the rate at which fuel is supplied or consumed within a system over a specified period.
Thrust Power - (Measured in Watt) - Thrust Power refers to the power generated by a propulsion system to produce thrust and propel an object forward.

STEP 1: Convert Input(s) to Base Unit

Fuel Flow Rate: 0.0315 Kilogram per Second --> 0.0315 Kilogram per Second No Conversion Required
Thrust Power: 54 Kilowatt --> 54000 Watt (Check conversion here)
