Could a free falling cylindrical tank pass down and through a gate mechanism into a compressed air chamber? Description of problem: A specially designed cylinder is allowed to free fall in a guided manner straight down into a tube which is part of a gate mechanism at the top of a compressed air chamber. The tube is lined with compression rings so as to maintain a tight seal with the cylinder as it passes down through the tube. Half way down this tube sits a gate. The gate is triggered to open just before the falling cylinder reaches it. The cylinder continues to fall passing through the now open gate and on down the tube. The cylinder continues down the tube and drops out of the bottom of the tube into a large compressed air chamber. The gate mechanism in the tube is triggered to close just as the cylinder exists the tube and enters the compressed air chamber. Specifics Tank Cylinder: 2 ft X 15 ft long Weight 2,645 lbs Cross sectional area of cylinder 3.14 sq ft. (452 sq inches) Tube cross sectional area just slightly larger than cylinder's to accomodate compression rings. Free fall distance for cylinder: 576 ft. Pressure of air in compressed air chamber 500 psi Length of Tube through which the cylinder must pass to enter the air chamber = 30 ft. (15 ft above the gate and 15 ft below the gate.) Compressed air chamber size 30 ft X 60 ft(deep) X 30 ft
