A trough is 9 meters long, 1.5 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 1.5 meters). The trough is full of water (density 1000kgm^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.)

9. (9 points) Suppose we have a triangular tank full of water. The tank is 2 meters long, half a meter tall and a meter wide (see below). Set up an integral for how much work is done when pumping water out of the top of the tank. Use p for the density of water and g for the acceleration due to gravity. Do not evaluate the integral. 0.5 m 1 m 9. (9 points) Suppose we have a triangular...

A straight ditch is 100m long and has the cross-section of a semi-circle of radius 1m. The ditch is full of water (density 103kg/m3 ) and we wish to calculate how much work is required to empty the ditch by pumping all the water to the top of the ditch where it can flow out through an overflow pipe. You should take the acceleration due to gravity to be g = 9.8m/s2 . (a) Draw a sketch of the ditch...
