The trough in the figure below has width w=4, lengthL=20 ft and height h=6.

If the trough is full of water, find the force of the water on a triangular end. (Use the density of water =62.4 lb/ft3.)
Force =

Find the work to pump all of the water over the top of the trough.
Work =

Step 1

The base, height and length are 4ft, 6ft and 20ft, respectively.

Then the thickness of the triangle is (4/6) h Δh.

The distance that get after slicing the triangle is (6 – h).
