Fluid Mechanics - Essay Example If the dimensions b and d of the immersed surface are 8.00 ft and 12.00 ft and the vertical distance is 10.00 ft., the magnitude of the resultant force on one side of the immersed surface is, 3. As indicated in examination Figure 1, assume that b = 27.00 in., d = 63.00 in., and h = 5.00 ft. The static moment of the immersed rectangular surface with respect to an axis in the surface of water, in feet to the third power. 4. As indicated in examination Figure 1, a rectangular plate is immersed in water in a vertical plane with its top and bottom edges horizontal. If b = 3.00 ft, d = 7.00 ft. And h = 2.00 ft, the vertical distance from the surface of the water to the center of pressure of the immersed surface is 5. A trapezoidal surface having the dimensions shown in Examination Figure 2 is immersed in fresh water with its top edge horizontal and at the surface of the water. The resultant force on one side of the immersed surface is 7. The formula to determine the moment of inertia of a rectangular surface with respect to a horizontal line drawn through its centroid is _________, where the surface’s width runs parallel to the line through the centroid. 8. a symmetrical trapezoid plate has the following dimensions. The width of the parallel are, respectively 2.50 ft. and 4.50 ft.The perpendicular distance between those sides is 1.50 ft. The plate is submerged in a liquid in a vertical position with the parallel sides horizontal and the shorter parallel side at the top and exactly even with the surface of the liquid. The moment of inertia of the plate with respect to the surface of the water would be, 9. a new cast iron pipe for conveying water from one reservoir to another has a diameter equal to 8.00 in., and the length is 5400.00 ft. The head tending to cause flow is 40.5 ft. If the velocity head and minor loses of head can be neglected, the rate of discharge, in cubic feet per second, computed by using the Chezy-Darcy
