If a cylindrical tank has a height of 50 ft and a radius of 9 feet with a thickness of 10 inches and a density of 100 lbs/ft. What would be the total weight when it's filled with water?
\n" ); document.write( ".
\n" ); document.write( "First, determine the volume of the space inside cylinder:
\n" ); document.write( "Inside radius = 9-10/12 = 8.1667 feet
\n" ); document.write( "vol = (pi)r^2h = (3.14)(8.1667^2)(50) = 10471.03 cubic feet
\n" ); document.write( ".
\n" ); document.write( "Vol of cylinder (outside diameter):
\n" ); document.write( "Outside radius = 9 feet
\n" ); document.write( "vol = (pi)r^2h = (3.14)(9^2)(50) = 12717 cubic feet
\n" ); document.write( ".
\n" ); document.write( "I'm assuming you meant 100 lbs/ft^3 to specify density...
\n" ); document.write( "Weight of cylinder:
\n" ); document.write( "(12717 - 10471.03)100 = 224597 lbs
\n" ); document.write( ".
\n" ); document.write( "Weight of water inside cylinder:
\n" ); document.write( "(assuming density of water is 62.42796 lbs/ft^3)
\n" ); document.write( "10471.03(62.42796) = 653685 lbs
\n" ); document.write( ".
\n" ); document.write( "Total weight:
\n" ); document.write( "224597 + 653685 = 878282 lbs \n" ); document.write( "
\n" );
