The radii of the two end-discs of a container (as shown) are r and r, (where r S rz in general) and its height h. I drill two identical holes at the centers of two end- discs to enable a draining constant k. Please do the following: (1) Compute the time t, needed to empty the fully-filled container when it is placed as shown. (2) Compute the time t, needed to empty the fully-filled (same liquid) container after you turn it upside down (3) Use your results above to show special cases. h r2 a) If r = r2, compute t /t, b) If r = 0, compute t1/t,
