The volume held in 1 cm length = 30*3.25*1= 97.5 cm^3\r
\n" ); document.write( "\n" ); document.write( "the volume held in 22 cms=
\n" ); document.write( "97.5 * 22 =2145 cm^3
\n" ); document.write( "..
\n" ); document.write( "1 sec flow is 2145 cm^3
\n" ); document.write( "60 seconds the flow will be 2145 * 60
\n" ); document.write( "=128,700 cm^3\r
\n" ); document.write( "\n" ); document.write( "1cm^3=0.001 liter
\n" ); document.write( "128700 cm^3= 128700*0.001
\n" ); document.write( "=128.7 liters
\n" ); document.write( "
\n" );
