Question 13.23: A rocket device burns its propellant at a rate of 0.0676 kN/...

A rocket device burns its propellant at a rate of 0.0676 kN/s. The exhaust gases leave the rocket at a relative velocity of 980 m/s and at atmospheric pressure. The exhaust nozzle has an area of 0.032 m², and the gross weight of the rocket is 2.2 kN. At the given instant, 2000 kW is developed by the rocket engine. What is the rocket velocity?
