Prime numbers from 1 to 50:
2, 3, 5, 7, 11, 13<span>, 17, 19, 23, 29, 31, </span>37,41<span>, </span>43<span>, </span><span>47</span>
The graph of this equation is shown in the figure below. We know that this equation is given as follows:

So, it is obvious that this is not a representation of a rain gauge. This graph represents a parable, but the rain gauge seems to be more like a <span>truncated cone</span>
