Question 19
XE-BNAT2 marksNeeds review
Air (of density 0.5 kg/m
) enters horizontally into a jet engine at a steady speed of 200 m/s through an inlet area of 1.0 m
. Upon entering the engine, the air passes through the combustion chamber and the exhaust gas exits the jet engine horizontally at a constant speed of 700 m/s. The fuel mass flow rate added in the combustion chamber is negligible compared to the air mass flow rate. Also neglect the pressure difference between the inlet air and the exhaust gas. The absolute value of the horizontal force (in kN, up to one decimal place) on the jet engine is__________.Log in to check the answer
