Fluid Mechanics

A primitive jet engine is fixed to a stationary test rig. The engine has an inlet area of Ai = 2.5 m2 and an outlet area of A0 = 0.5 m2. Ambient air (Ti = 298 K,P= 101 kPa) enters the engine at a flow rate of mi = 10 kg s-1. Fuel with a heating value of qf = 43 MJ kg-1 flows into the engine at deltam = 0.1 kg s-1, and is mixed with the air and combusted. Determine the thrust produced by the engine. Note: you may assume that the air and air-fuel mixture are perfect gases with: R = 287 J kg-1 Answer him: 382 N
