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.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
