By using excel to run this equation Using Visual Basic ( devolper ) and

Theory The volume of a cylinder can be calculated by: The volume of the frustum of a cone can be calculated by V -wh(ri rirz r The dimensions of a tank are defined by heights H1 and H2, and radii ri and rz, and shown in the diagram. The calculation for fluid volume is different if the measured height, h, is above or below H1. If h s H (r2-ra)(h-H,) If h H r1 H2 While the above formulas will calculate the volume in cubic feet, it is common to speak of volume of a liquid in gallons. One cubic foot is equivalent to 7.481 gallons
