### How to measure volume using a Measuring Cylinder

A measuring cylinder is laboratory equipment, used to measure the volume of a liquid. Also, popular as graduated cylinder or mixing cylinder, the measuring cylinder provides more accurate and precise measurement than other laboratory flasks and beakers.

The * measuring cylinders* come in various sizes ranging from 10 ml to 1,000 ml. The readings are taken after measuring the lowest portion of the meniscus.

**What is meniscus?**

As per the information available through various sources, the meniscus is the lowest portion of the convex dip of the liquid as it settles in the measuring cylinder.

**What is the reason of meniscus formation?**

The formation of meniscus takes place due to the attraction of water molecules within the walls of the measuring cylinder. It is based on the principle that states- “Adhesive forces are stronger than cohesive forces”.

**Steps involved in measuring or calculating the volume of a measuring cylinder**

In order to calculate the volume with the help of a measuring cylinder, you will have to find the height (h), and the radius (r) of the cylinder and put it into a simple formula- V = hπr2. The steps are given below:

- First, find the radius of the circular base of the measuring cylinder. If you know the diameter of the circle then you can divide it by 2 or if you know the circumference, then you have to divide it by 2π.
- Second, calculate the area of the circular base. The formula for calculating the area of a circle will serve the purpose here, A = πr2.
- Third, find the height of the cylinder. You can use a scale or a ruler to measure the height. The height is basically the distance between the edges of the two bases.
- Fourth, after finding the area and the height, you have to multiply the area of the circular base by the height of the cylinder as the formula for measuring volume is V = hπr2.

**Note:**

The volume is always represented in cubic units because it is the measure of a three-dimensional space.

The π is about the equivalent of 22/7.

**Some tips to remember during the measurement**

- Make sure that you have taken accurate measurements during the volume measurement process.
- If you are not sure of your own calculations then go for a calculator. This will make your work easy and less time-consuming.
- “Practice makes a man perfect”- this phrase works here too. Make up a few problems and practice it before you get down to do the process in real.
- Memorise the necessary formulas involved so that during the process, you don’t have to struggle for it.
