Gross thrust Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gross Thrust = Mass Flow Rate*Exit Velocity
T_G = m_a*V_e
This formula uses 3 Variables

Variables Used

Gross Thrust - (Measured in Newton) - Gross Thrust is the total thrust of a jet engine without deduction of the drag caused by the momentum of the incoming air.
Mass Flow Rate - (Measured in Kilogram per Second) - Mass Flow Rate represents the amount of mass passing through a system per unit of time.
Exit Velocity - (Measured in Meter per Second) - Exit Velocity refers to the speed at which gases expand at the exit of nozzle of a engine.

STEP 1: Convert Input(s) to Base Unit

Mass Flow Rate: 3.5 Kilogram per Second --> 3.5 Kilogram per Second No Conversion Required
Exit Velocity: 248 Meter per Second --> 248 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_G = m_a*V_e --> 3.5*248

Evaluating ... ...

T_G = 868

STEP 3: Convert Result to Output's Unit

868 Newton --> No Conversion Required

FINAL ANSWER

868 Newton <-- Gross Thrust
