Set up integrals to compute the total volume in m^3 of and the total work in Joules to pump all of the water out of the following tanks. Assume that the density of the water is a uniform 1000 kg/m^3 and that the acceleration due to gravity is a constant 9.8 m/s^2.

b.) An inverted, square-based pyramid (top side length 6 * sqrt(2) m, bottom side length 3 * sqrt(2) m, height 3 m), completely filled to the top with water and pumped just over the side of the tank.

Consider a hemispherical tank with a radius of 3 meters that is resting upright on its curved side. Using 9.8 m/s^2 for the acceleration due to gravity and 1,000 kg/m^3 as the density of water, Set up the integral for the work required to pump the water out of the tank if: (a) the tank is full of water and it is being pumped out of a 1-meter long vertical spout at the top of the tank. (b) the tank...

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 trough is 10 meters long, 3 meters wide, and 4 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isosceles triangle (with height 4 meters, and base, on top, of length 3 meters). The trough is full of water (density 1000kg/m^3). Find the amount of work in joules required to empty the trough by pumping the water over the top. (Note: Use g=9.8ms^2 as the acceleration due to gravity.)

A tank is filled with 8m water (density water = 1000 kg/m^3) and 2 m oil (density oil = 900 kg/ m^3).Flow is discharged at the bottom from a circular exit section with 5 mm diamter. Ignoring all frictional effects, determine the a) Velocity in exit section if the top tank pressure is atmospheric b) Flow rate in exit section if the top tank pressure is -25 kPa vacuum.

A valve shaped like a triangle of base 3 meters and height 2 meters is submerged vertically 3 meters below the surface of the water in a tank. a. Assuming that the tank is full, use the techniques learned in Chapter 2.5 to set up a definite integral of the total fluid force ? on a side of the valve. b. Calculate the fluid force ? (in Newtons). Use 1000 kg/?3 as the mass density of water and ? =...

Darcy's law gives us the volume flow rate-volume per time (for example, cubic meters per day, m^3/day). Another way to express volume is on a per-unit-area basis. For example, if we have a 1-m^3 cube, we know its base is 1 m^2 the cross-sectional area of the cube-and its height is 1m. If we fill the cube with water, we can say we have 1m of water per unit area. Darcy's law can be rearranged to calculate the volume flow...
