How to calculate water tank capacity in liters

To calculate water tank capacity in liters, you need to know the tank’s dimensions (length, width, height) in meters. Then, multiply these dimensions to find the volume in cubic meters and finally, convert cubic meters to liters (1 cubic meter = 1,000 liters).

There is necessity of water tank in residential, commercial and industrial building, restaurants, hotel, hostel and others for many purpose like drinking, cooking, bathing and toilet, washing clothes, utensil cleaning, house cleaning and for others domestic uses.

For multi storey building, apartment, commercial and for industrial building there is a given design and plan of water tank facility to provide water in the house with the design and plan of house, so there is no need to calculate water tank capacity.

But for normal residential building in a small cities and in rural areas, if plan of water tank is not available with plan of house, so there is need of water tank in house for providing water facility for family members and they want to construct own methods cylindrical and rectangular water tank according to water requirement in their house for family members and they want to know about how to calculate water tank capacity.

As per Indian standard there is a need of about 135 liters of water per head per day for many domestic uses, about 5 liters of water required for drinking, 5 liters for cooking, 85 liters for bathing and toilet, 30 liters for washing cloth and and 10 liters for cleaning house.

About 135 liters of water require per day by per person, so family members of 4, 135×4= 540 liters, you will require about 540 liters of water per day for 4 family members, for 8 users you will require about 1080 liters of water, for 10 users you will require about 1350 liters of water, for 20 users you will require about 2700 liters of water, for 25 users you will require about 3375 liters of water, for 50 users you will require about 6750 liters of water, for 75 users you will require about 10000 liters of water and for 100 users you will require about 13500 liters of water.

Design and plan of water tank should be made according to daily requirement of water in the house based on number of users, in restaurant, hotels, hostels, Industrial and commercial building there is a need of huge amount of water so there water tank dimension should be larger, in residential small building there is a few user so there is necessity to construct a small water tank.

How to calculate water tank capacity in litres? To find the typical capacity of the water tank in litres, multiply the volume in m3 by 1000, because 1 m3 = 1000 litres. The total volume of the water tank is calculated by multiplying the area (A) by the height H.

How to calculate the capacity of the rectangular water tank in liters? To find the typical capacity of the rectangular water tank in litres, multiply the volume in m3 by 1000, because 1 m3 = 1000 litres. The total volume of the rectangular water tank is calculated by multiplying the area (A) by the height H.

How to calculate the capacity of the cylindrical water tank in liters? To find the typical capacity of the cylindrical water tank in litres, multiply the volume in m3 by 1000, because 1 m3 = 1000 litres. The total volume of the round water tank is calculated by multiplying the area (A) of round end by the height H.

How to calculate water tank capacity

There is two types of water tank rectangular water tank and cylindrical water tank, measuring the volume of water tank is capacity of water tank.

To find the capacity of a rectangular or round (cylindrical) water tank in litres, multiply the water tank volume in cubic feet by 28.317 liters per cubic foot or multiply the water tank volume in cubic meters by 1000 per cubic meter.

Formula to calculate capacity of water tank in litres = volume of water tank in cubic feet × 28.317 liters or volume of water tank in cubic meter x 1000. For example, if volume of rectangular water tank is 50 cubic feet, then capacity of water tank in liters = 50 x 28.317 = approximately 1,416 litres

In this regard, “how to calculate water tank capacity”, to answer this it is very simple, for rectangular water tank capacity, total volume of rectangular water tank equal as capacity, measure the Length, breadth and height of tank in meters as 2m × 1m × 0.5m, multiply 2m × 1m × 0.5m= 1m3, you get volume of water tank it can hold 1 cubic meter, multiply the answer by 1000 as 1×1000= 1000 liters, the result 1000 is water tank capacity in liters.

Or for cylindrical water tank capacity total volume of cylindrical water tank equal as capacity, total Volume of Cylinder shaped tank is the area A of circular end times the height H, A= π R^2, where R is the radius which is equal to 1/2 of diameter or d/2, therefore volume of Cylinder shaped water tank V tank = π R^2 × H, if diameter = 1.12m and height is meter, than R = 1.12/2 = 0.56m, so volume of tank = 3.14 × 0.56 × 0.56 × 1 = 0.984m3, nearly equal as 1m3, multiply the answer by 1000 as 1×1000= 1000 liters, the result 1000 is water tank capacity in liters.

In this regard, “how to calculate water tank capacity in liter”, to answer this it is very simple, for rectangular water tank capacity, total volume of rectangular water tank equal as capacity, measure the Length, breadth and height of tank in meters as 2m × 1m × 0.5m, multiply 2m × 1m × 0.5m= 1m3, you get volume of water tank it can hold 1 cubic meter, multiply the answer by 1000 as 1×1000= 1000 liter, the result 1000 is water tank capacity in liter.

How to calculate circular water tank capacity

To calculate capacity of circular (round) water tank in liters, multiply volume of water tank in cubic feet by 28.317 litres per cubic feet or multiply volume of water tank in cubic metres by 1,000 per cubic meter. Formula for capacity of water tank in liters = Volume of water tank in cubic feet × 28.317 liters or volume of water tank in cubic meter x 1000. For example, if your volume of circular or round water tank is 1.5 cubic meter then capacity of water tank = 1.5 x 1000 = 1500 liters.

To determine round water tank capacity in liters you can proceed with following calculation steps:-

1) measure the diameter and height of water tank such as diameter = 1.2 meter, Height = 0.9 meter

2) convert diameter into radius, that is R= d/2 or 1.2/2 = 0.6 meter

3) measure the area of circular end, A= πR^2, as Area = 3.14 × 0.6 × 0.6 = 1.13 sqm

4) calculate volume of circular water tank by multiplying area and height as V tank = Area × H, as Volume = 1.13 sqm × 0.9 m = 1m3,

5) you get volume of water circular tank it can hold 1 cubic meter, multiply the answer by 1000 as1×1000= 1000 liters, the result 1000 is circular water tank capacity in liters.
