A diving pool that is 7m deep and full of water has a viewing window on one of its vertical walls. Find the force on a window that is a square, 1.5m on a side, with thr lower edge of the window on the bottom of the pool. Use 1000 kg/m^3 for the density of water and 9.8 m/s^2 for the acceleration due to gravity. Find the width function w(y) for each value of y on the face of the window.

A vertical dam has a semicircular gate as shown in the figure. The total depth d of the figure is 42 m, the height h of air above the water level is 6 m, and the width w of the gate is 8 m. Find the hydrostatic force against the gate. (Round your answer to the nearest whole number. Use 9.8 m/s2 for the acceleration due to gravity. Recall that the weight density of water is 1000 kg/m3.)

A trough is 9 meters long, 2 meters wide, and 3 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 3 meters, and base, on top, of length 2 meters). The trough is full of water (density 1000 kg m 3 1000 kg m 3 ). Find the amount of work in joules required to empty the trough by pumping the water over the top. (Note: Use g =...

A dam on a river is built so that the wall facing the water is shaped like the region above the curve y=0.3 x^4 and below the line y= 140 . (Here, distances are measured in meters.) The water level is 20 meters below the top of the dam. Find the force (in Newtons) exerted on the dam by water pressure. (Water has a density of 1000 "kg"/m^3, and the acceleration of gravity is 9.8 m/sec^2 .)
