The question :
A turbofan engine on a test stand in the maintenance shop is being run at a continuous setting of 22,700 lbs of thrust. The TSFC is 0.5 lbs/lb-h. A fuel reservoir of 1000 gallons of JET A is feeding the engine. How long can it run at this power setting in minutes? A gallon of JET A weighs approximately 6.7 lbs.

Thrust, F = 22700 lbs
TSFC= 0.5 lbs/lb-h
Mass of fuel in the reservoir = 1000 gallons= 6700lbs
The solution contains detailed step-by-step explanation pertaining to Thrust Specific Fuel Consumption(TSFC) of turbofan engine.
