In essence, all you need to do it enter any two variables you know and the GPM calculator will determine the third one. To find time - e.g., how long it'll take to fill a pool:Įnter the volume of a container in the first field of the GPM calculator.Įnter the flow rate of water in the last field. You'll find the result in the 'Volume' row. Reset the water flow rate calculator using the arrow symbol below it. This tank capacity calculator finds the total volume of the given tank and the volume of the liquid in the tank for situations when the tank is not completely full. Water height is taken into consideration as well so only the portion of the tank filled with water is included in the result. Dividing by 231, which is the number of cubic inches in a gallon, will tell you exactly how many gallons your tank will hold when filled to capacity. Press the ÷ button, then enter 231 and hit a second time. Water volume is calculated using the formula of 7.48 US gallons per cubic foot of volume. Divide the tanks volume in cubic inches by 231 to convert to gallons. Enter the dimensions to calculate your tank’s water volume. To find volume - e.g., know how much water you'll use for a 15-minute shower : Choose the tank shape that closely resembles the shape of your aquarium. Thats all The general formula for a regular octagonal pyramid reads: V 2 × (1 + 2) / 3 × a² × h.

You can change it to a different GPM unit as you please. The below given is the online volume of water calculator cylinder to calculate the liquid volume filled in a vertical, horizontal, rectangle, horizontal oval, vertical oval, horizontal capsule and vertical capsule cylinder. To get the volume of a regular octagonal pyramid with a side length of a and a height of h: Square the side length to get a². You'll find the flow rate in the last field of the gallons per minute calculator. Input the volume of the liquid in the first field.Ĭhoose the unit of time in which the given volume of water flowed. For a myriad of other units of volume, you may find our separate volume calculator very interesting. Calculate the volume of liquid your container can hold by entering your dimensions in metric units (centimeters or meters) or imperial units (yards, feet or inches). Accounting for unit conversions and steel density of 7850 kg/m3, the following approximate formula is used for TMT steel bars: W d2l/162. where: d Rods diameter in m l Rods length in m and. To find the flow rate - e.g., when you ask ' How many gallons per minute does a shower use?', follow the points below:Ĭhoose the unit in which you will count the volume. The steel weight formula for a cylindrical steel rod/bar is: W (/4)d2l.
