What is the capacity of a washing machine drum in liters?
To calculate the drum volume of a washing machine in liters, you'll need to remember not only math but also high school geometry. Plugging the values into the arithmetic formula isn't that difficult, but getting the raw numbers is much more challenging. Let's figure out what to measure in a centrifuge to determine the tank's capacity.
How to take measurements?
If you need to know how many liters of water your washing machine's drum holds, you can try searching online. Many manufacturers list this figure alongside other technical specifications. If the model description or instructions don't provide the necessary information, you'll have to calculate it yourself.
To calculate the volume of the drum of an automatic washing machine, you need to know the area and radius of the base, as well as the height of the container.
A washing machine drum isn't perfectly shaped and has concave sections, so achieving a perfectly accurate measurement will be difficult. There will always be some margin of error. To calculate the volume of a cylinder, you need to substitute the initial data into the formula: V = 3.14*R^2*H. Where:
V – volume of the container;
H – cylinder height;
R – radius of the tank base;
3.14 is the number “Pi”, known to everyone since school geometry.
As an example, we will indicate the drum capacity of some washing machines of different brands, and how much laundry can be loaded into such a machine.
Candy CS34 1052D1/2. The machine has a 5 kg capacity. The actual load capacity is 4.77 kg. The drum capacity is 47.74 liters.
Weissgauff WM 4126 D. This model features a 6 kg drum, which holds 5.62 kg of laundry. The tank capacity is 55.51 liters.
Haier HW70-BP12969BS. The manufacturer claims the machine can wash 7 kg of laundry at a time, but in reality, the maximum load is 6.59 kg. The centrifuge capacity is 62.22 liters.
So, if you urgently need to know the drum capacity of your washing machine in liters, check the manufacturer's website. This information is often included in the model description. If you don't have this information, measure the required capacity parameters yourself and plug the values into the formula.
Why do we need to know this?
Many housewives believe that at least 10 liters of water are needed to wash one kilogram of laundry to its full potential. This wisdom has been passed down from grandmothers to granddaughters and mothers to daughters since Soviet times. Of course, engineers are now trying various tricks to save water, but it's hard to fool nature. In fact, the more liquid the laundry is rinsed in, the better the dirt will be washed out of the fabric fibers.
That's why housewives are more concerned with the drum capacity in liters than with the maximum load capacity, which is always stated by the manufacturer. For example, in a Candy CS34 1052D1/2 washing machine with a 5 kg capacity and a 47.74 liter spinner, it's best to wash no more than 4 kg of laundry at a time.
The same applies to other washing machines. When the manufacturer states that the machine is rated for 8 kg of laundry, it's best to subtract 1 kg from that figure. If you load more than 7 kg of laundry into the drum, the clothes will not wash properly.
It's important not to confuse the tank and drum volumes. The tank is larger and holds more water. From the plastic container, the soap solution flows into the centrifuge and into the laundry through numerous small holes in the metal tank.
It's a shame that finding out the centrifuge capacity of a washing machine requires such complicated calculations. Is it difficult for manufacturers to tell this up front, or do they deliberately want to keep it under wraps?

Thank you. I found out everything I needed to know.
