The power generated by a wind turbine is proportional to the cube of the wind velocity. Inspired by the acceleration of a fluid in a nozzle, someone proposes to install a reducer casing to capture the wind energy from a larger area and accelerate it before the wind strikes the turbine blades, as shown in Fig. P5-145. Evaluate if the proposed modification should be given a consideration in the design of new wind turbines. Problems designated by a C are concept questions. and students are encouraged to answer them all. Problems designated by an E are in English units, and the SI users can ignore them. Problems with the icon are comprehensive in nature and are intended to be solved with appropriate software. 248

A cylindrical 125 cm high and 89 cm diameter, as given by the figurethe inside of the tank is initially completely filled with oil. Then 1.25 to the base edge of the tanka hole in diameter of cm is opened and the oil begins to drain from this hole. Oil output speed from tank(2gh)-1/2is given as. (h, the variable height of the oil inside the tank from the center of the holeand G indicates the acceleration of gravity). From the base of the oil level inside the tankCalculate the time it takes to fall to a height of 15 cm in [s].
Consider a cubical water tank with a side length of 3 m. The tank is half filled with water, and is open to the atmosphere. Now, a truck carrying this tank is accelerated at a rate of 5 m/s2. The maximum vertical rise of free surface of the water is (a) 1.5 m (b) 1.03 m (c) 1.34 m (d) 0.681 m (e) 0.765 m
A man is standing on a board on a frozen lake where there is no friction between the board and the ice surface. Tha man's mass is 2 m and the boaf's mass is 4 m. The board has length L. He walks from 1/5 Lfrom the left end of the board to 1/5 L from the right end of the board. How far and in which direction does the board move during this process?
