"consider a rectangular wing mounted in a low-speed subsonic wing tunnel. the wing model completely spans the test-section so that the flow "sees" essentially an infinite wing. if the wing has a naca 23012 airfoil section and a chord of 0.3 m, calculate the lift, drag, and moment about the quarter-chord per unit span when the airflow pressure, temperature, and velocity are 1 atm, 303 k, and 42 m/s, respectively. the angle of attack is 8°.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
