The thrust of the jet engine is determined as 9,970.2 N.

The power delivered by the jet engine is 2.293 x 10⁶ W.

How to calculate the thrust and delivered power?

The thrust of the jet engine is calculated by applying the following formula as shown below.

F = (m₁ + m₂)V₁ - m₁V

where;

  • m₁ is the mass rate of air flow
  • m₂ is the mass rate of the fuel flow
  • V₁ is the speed of exhaust gases
  • V is the speed of the jet

F = (96.7 + 3.96)320 - 96.7 x 230

F = 9,970.2 N

The power delivered by the jet engine

P = FV

P = 9,970.2 x 230

P = 2.293 x 10⁶ W

The complete question is below:

A jet aircraft is traveling at 230 m/s in horizontal flight. The engine takes in air at a rate of 96.7 kg/s and burns fuel at a rate of 3.96 kg/s. The exhaust gases are ejected at 320 m/s relative to the aircraft find the thrust of hte jet engine find the delivered power
