MAE 113 Winter 2008
Common Errors in HW 2
1.6: -Not using equations for a bypass engine
1.8: -Not using equations for a bypass engine, and instead used the equation for an engine with a single inlet/exhaust
2.6: -Sign errors, confusing the direction the forces will act
2.8: -Same errors with signs as problem 2.6
-Neglecting atmospheric pressure in the equations
-Attempting to compute a mass flow at the exit when
the mass flow at the entrance is given, and there is a single
inlet/outlet
All problems: -Not paying attention to units
