Knowing your aquarium's dimensions, volume and water contents are key in determining the appropriate pumps and other equipment, as well as chemical additives needed to maintain the environment as comfortable for the fish as possible and making sure you enjoy the company of your pets for longer. Reasonable approximations can be made for slightly irregular shapes by taking the average length or width, but in more complex scenarios and the need for an accurate water estimation you should consult a professional since it will likely require integral calculus. In case you end up needing to do this for a large number of sections, you might use our summation calculator. In such cases what you want to do is divide it in several rectangular-shaped sections, calculate their volume and water requirements using our calculator then sum them up together. In some cases, the aquarium will have an irregular shape, for example the outer walls may be curved instead of straight. Volume and water calculations for non-rectangular aquariums However, "size" would mean the external or internal dimensions of the aquarium, not its volume, although the two are related.
Some people incorrectly refer to the volume of an aquarium as "aquarium size". When using this aquarium calculator, you should consider that the depth of the aquarium may not be the whole depth from top to bottom, but only the depth to which it can actually be filled. The density of water is ~62.2347 lb/ft 3 (997 kg/m 3) at room temperature. To get the water weight, multiply the volume by its density (in the same units).Convert the volume to litres or gallons, depending on the unit you want the result to be in.Estimate the volume of water that will fill the aquarium by taking measurements or using the product specifications.In either case the calculation process would be: Calculations for the weight of the water the aquarium will contain are required when deciding where you would like to place it. since they all depend on the aquarium's volume. oxygen pumps, air pumps, oxydators), chemicals, etc. An aquarium volume calculator is usually consulted as a part of an estimation for the cost of maintaining the aquarium, including the water cost and the cost of appropriate aerators (a.k.a. One often needs to calculate the volume of an aquarium in order to determine the amount of water needed to fill it. Volume and water calculations for non-rectangular aquariumsĬalculating aquarium volume and water needed.Calculating aquarium volume and water needed.Step 4. Set up the cancellation table so all units will cancel, except the desired unit, gallons. Step 1. Use the equation for determining the volume of a cylinder.
What is the capacity, in gallons, of the tank? The base of a cylinder is a circle, A = π × r 2, where π = 3.14.Įxample 3 - A cylindrical tank of foam concentrate is 5 feet tall. The volume of a cylinder is found by multiplying the area of the base times the height, h.
The volume of the tank is 170 cubic feet or 1272 gallons. Step 5. Set up the cancellation table so all units will cancel, except the desired unit, gallons. Step 4. Set up the problem, and solve for volume. Step 3. Convert all the measurements to the same units, feet. Step 2. Identify the length, width, and height. What is the capacity of the water tank in cubic feet? In gallons? The volume of the tank of water is 240 cubic feet or 1,795 gallons.Įxample 2 - The water tank on a newly designed engine is 34 inches wide, 5 feet high, and 12 feet long. Step 5. Set up the cancellation table so all units will cancel except gallons (see Section 2.1). Step 4. Determine the appropriate conversion factor. Step 1. Use the equation for determining the volume of a rectangle. The volume of a rectangular container is determined by multiplying the length (l) by the width (w) by the height (h).Įxample 1 - Determine the volume of the tank in gallons. It is used by firefighters to answer questions like "How much water is left in the tank?" and "At 15 gallons per minute (gpm), how many more minutes before the tank is empty?" Volume is used to indicate the capacity of a tank or container.
