Thrust specific fuel consumption Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thrust-Specific Fuel Consumption = (3600*Fuel Air Ratio)/Specific Thrust
TSFC = (3600*f)/I_sp
This formula uses 3 Variables

Variables Used

Thrust-Specific Fuel Consumption - (Measured in Kilogram per Second per Newton) - Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output.
Fuel Air Ratio - Fuel air ratio is the ratio of mass flow rate of fuel to the mass flow rate of air.
Specific Thrust - (Measured in Meter per Second) - Specific Thrust is the thrust produced per unit mass in per unit time.

STEP 1: Convert Input(s) to Base Unit

Fuel Air Ratio: 0.009 --> No Conversion Required
Specific Thrust: 137.02 Meter per Second --> 137.02 Meter per Second No Conversion Required
