\n" ); document.write( "\n" ); document.write( "The idea is to find the net inflow rate as the difference of the inflow rate and outflow rate,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and then to divide the total volume of the tank by the net inflow rate.\r
\n" ); document.write( "
