Question 825275
Do everything in meters, and convert to centimeters for height at the end of the process.


Flow rate is in terms of length of water as if it were a tube.  Cross section area is {{{pi*0.06^2}}} {{{m^2}}} and for 2.5 hours of flow time, this is a volume of {{{(18*1000*meter/hour)(2.5*hours)*(pi*0.06^2*meter*meter)=18000*2.5*pi*0.06^2*meter^3}}}
{{{508.938*meter^3}}}


Now, what is the height in the tank in meters?
Let h = height in meters, to be later converted into centimeters;
{{{30*16*meter*meter*h*meter=508.938*meter^3}}}
{{{highlight(h=508.938/(30*16)*meter)}}}
h=1.06 meters, or 106 centimeters.
