The volume of an elliptical cylinder equals the product of the semiminor and semimajor axes, the length of the cylinder and \Pi. If you cut out a known area and weigh it, you have the weight per unit area used to find the unknown area. An elliptical cylinder is a cylinder whose cross-section is an ellipse. You cut the shape out and accurately measure the weight. I first heard of this type of procedure to try to find the area of a very irregular surface. An oval volume is a three dimension object with an oval or elliptical base and top and vertical sides (see diagram above). This method should work even if the dipstick is not vertical. Remember the cut line dividing the semicircle must always be parallel to the straight edge of the semicircle.ĭo some elementary math to proportion the heights of the pieces to establish the place to mark the truck dipstick. There are a million ways to do this - if you have a precision micro-balance you are better off than most!īalance the two pieces of the semicircle and keep cutting semicircles until the pieces balance as accurately as you have the patience. one US gallon of diesel fuel 7.1 pounds one US gallon of gas 6 pounds. This calculator uses inches for measurements. The elliptical cylinder tank looks like a squashed cylinder. Make a primitive balance with a rod or stick and,say, thread or whatever. Calculate a vertical cylinder tanks volume, capacity, and surface area. Make sure that the line and edge are parallel. The formula uses the radius of the cylinder. The result of the cos-1 function in the formula is in radians. one cubic inch (in) 0.000578703703703704 cubic feet (ft) one cubic inch (in) 0.000016387064 cubic metres (m) one cubic inch (in) 0. As a formula volume where: R is the radius of the cylinder. V HWL/4 where V is the volume 3.14159265 H is the height of the tank W the width L the length. (You will probably need several semicircles as this is a iterative process.)ĭraw a line parallel to the straight edge of the semicircle where you think the 25% level may be. full tank liquid weight based on lbs/gal US. The Bioscape 120 Ultra Clear Glass and Bioscape 60cm Ultra Clear Glass Aquarium Tanks are. Think of it as filling up the space within the tanks dimensions. Draw a circle on a piece of cardboard and cut it into two equal semicircles. To find the volume of a rectangular aquarium, you need to multiply the height, width, and length of the tank.
