# Homework Help: Water Pressure in tank filled with water

Figure 14-24 shows a tank filled with water. Five horizontal floors and ceilings are indicated;
all have the same area and are located at distances L, 2L, or 3L below the top of the tank. Rank them according to the force on them due to the water, greatest first.

Are we just comparing the heights?
So e>b=d>a=c?

Thanks!

Yes, essentially, since they're all of the same area and in the same horizontal orientation. The answer is correct.

If you need to show working, the key points to include are the equations $p = h{\rho}g$ and $F = pA$.
