Exhaust Gas Stream Velocity
Dear Reader,
My Dad was asking me if I knew at what speed the stream of exhaust gases is doing when it comes out the back of a jet engine. He used the example of a B747 at 400 kts. I appreciate the answer my depend on the type of engine concerned, power setting, atmospheric conditions and so on. I was unable to answer his question and I was wondering if there were any RR, P&W, or GE types out there who could provide an answer. Are there any takers?
