# How to Measure Volume

A Graduated Cylinder is one of the most common instruments used in the lab to obtain the volume measurements of liquids. It is also known as mixing or measuring cylinder. Its shape is narrowing cylindrical. The lines that are marked on the cylinder signify the value of the volume that has been measured through observing the ends of the liquid droplets on the cylinder.

**Check the Marks on the Cylinder**

The graduated cylinder has various capacities; each has its own specific graduation marks on the outer surface. Though there is a general capacity and that is 5ml to 500 ml. So, first, it must be known that each graduation mark corresponds to how much of the volume value. Ensure that the graduation cylinder that is purchased is from a verified seller and check the surface for any defects that might be prevalent. The most common ones are breaks which appear at the tip ends and do not carry measurements if there are any discrepancies on the surface. Further, also ensure that there are the starting and the ending graduation on the cylinder. And scan briefly to ensure that equal spacing exists between them. A beaker, flask or conical is employed as a graduated cylinder to measure the liquid volume, let’s take water here. However, their sign of volume is an approximation, therefore, to get a result as higher accuracy a marked cylinder would be more appropriate.

- Graduated cylinder n deg 1- The volume between two graduations corresponds to 10mL.
- Graduated cylinder n deg 2- The volume between two graduations corresponds to 2mL.
- Graduated Cylinder n deg 3- The volume between two graduations corresponds to 1mL.

**Undertake the Measurements**

Now, in order to begin the measurements, the graduation marks that are closest to the other end of the cylinder that is the free surface of that particular liquid must be known or determined. Then, the observer must watch the marking from the same level as the graduation in order to avoid the parallax error. Not above, not below, at the exact level as a free surface.

**Do the Math**

Using the earlier information and some Math, the volume can now be calculated. For example:

If the liquid is one mark below 100, then, we can calculate the volume as follows:

- 100- 10= 90; Volume= 90 ML

If the liquid is two marks above 5, then, the calculation will be as follows:

- 5+2=7; Volume= 7 ML

If the liquid is one mark above 100, then, the calculation would be as follows:

- 100+10=110; Volume= 110 ML

Note that, due to the capillary effect of the water, the droplets might get attached to the walls of the cylinder in which the measurement is being taken. This process might not be widely seen in the case of wide cylinders but are very prevalent in narrow cylinders. In order to correctly measure the volume, one must make sure that the lower surface of the liquid droplet is taken as the reference and this, in other words, is also known as the lower meniscus.

### How do we measure volume?

### What are three ways to measure volume?

**volumes**will be determined by

**three**different

**methods**: geometrically (

**measuring**lengths); water displacement; and pycnometry. The composition of a mixed brass-aluminum cylinder and the

**volume**of empty space within a hollow cylinder will also be found.

### What is the easiest way to find volume?

**Units of**

**Measure****Volume**= length x width x height.- You only need to
**know**one side to**figure**out the**volume**of a cube. - The units of
**measure**for**volume**are cubic units. **Volume**is in three-dimensions.- You can multiply the sides in any order.
- Which side you call length, width, or height doesn’t matter.

### How do you find the volume of a cup?

### How do you find out the volume of a shape?

**Volume**is the amount of space a 3D

**shape**takes up.

This is written as 1 cm³. You can work out the **volume of a shape** by multiplying height × width × depth.

### How do I find the volume of an irregular shape?

**volume**of this box-

**shaped**space by multiplying its length, width, and height together (length x width x height). The answer to this multiplication problem is the

**volume**of the

**object**. Do not measure the height of the entire container, just the height from one water mark to another.

### What is the formula for volume of a prism?

**volume**of the

**prism**shown. The

**formula**for the

**volume of a prism**is V=Bh , where B is the base area and h is the height. The base of the

**prism**is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

### What is the volume of this cylinder?

**volume**of a

**cylinder**is V=Bh or V=πr2h . The radius of the

**cylinder**is 8 cm and the height is 15 cm.

### How do you find volume with diameter?

### What is the area and volume of cylinder?

**cylinder’s volume**is π r² h, and its surface

**area**is 2π r h + 2π r².

### How do you calculate the volume of a tank?

**formula**of

**volume**of the rectangular

**tank**is given as, V = l × b × h where “l” is the length of the base, “b” is the breadth of the base, “h” is the height of the

**tank**and “V” is the

**volume**of the rectangular

**tank**.

### How do I calculate tank volume in Litres?

**volume**(in cubic centimeters) of the shape by 1,000 will give you the

**volume in liters**(

**L**). . So, a fish

**tank**that is 40.64 cm long, 25.4 cm wide, and 20.32 tall has a

**volume**of 20.975

**L**.

### How do you calculate volume in Litres?

**calculate**the number of

**litres**, you then divide that number by a million. As an example, let’s take a box

**measuring**406 x 356 x 203mm.

### Is capacity the same as volume?

**Volume**and

**capacity**are properties of three-dimensional objects.

**Volume**is the space that a three-dimensional object occupies or contains;

**capacity**, on the other hand, is the property of a container and describes how much a container can hold.

### What is the volume and capacity?

**Volume and capacity**is the measure of the amount of space inside of a solid object, such as a cube, ball, cylinder or pyramid. It is measured in cubic units.

### How do you explain volume and capacity?

**Volume**is the amount of space a container or object occupies.

**Capacity**is the amount of water required to fill the fish tank (ml or L).

**Volume**is the space the tank and water take up. The most common unit of

**volume**is centimetres cubed (cm3).

### What is volume to capacity ratio?

**Volume-to-Capacity ratio**(V/C) measures the level of congestion on a roadway by dividing the

**volume**(VPD) of traffic (existing or future) by the

**capacity**of the roadway. Example: if the

**volume**of traffic on the roadway were 10,000 VPD, then the V/C

**ratio**for that segment would be 10,000/17,400 = .

### How do you convert volume to capacity?
