Consider the wing– body model in problem 2. the area and chord of the wing are 0.15 m2 and 0.15 m, respectively. now assume that a horizontal tail is added to this model. the distance from the airplane’s center of gravity to the tail’s aerodynamic center is 0.25 m; the tail area is 0.04 m2 ; the tail- setting angle is 3°; the tail lift slope is 0.1 per degree; and from experimental measurement, = 0 and = 0.4. if = 8°, calculate for the airplane model.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
