A wing has a lift-curve slope of 5.2 per radian, and the product of eAR is 8. Given that a second wing has an effective aspect ratio (eAR) of 6.0 and the same airfoil as the first wing, how fast must this second wing travel in order to lift 3000 lbs. when it is at an angle of attack of 6.0 degrees. The area of the second wing is 300 ft2, and the angle of zero lift angle is -1.0 degree. Assume that both wings are operating at standard sea-level conditions.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
