# Specific weight and volume question

• dfcitykid
In summary, the conversation discusses a problem involving tanks filled with water and their specific weight of 9.45 kN/m^3. The problem also provides a range of volumes for different tank sizes and asks for the added weight (kN) due to the liquid for the given range of diameters. The person asks how to calculate the added weight and if they should simply add the different volumes to the specific weight. They are advised to re-upload the question in the homework help section for more assistance and to include their attempted solution.

So I have a problem/question were tanks are filled with water and its specific weight is 9.45 kN/m^3. They also give you a range of volumes of different tanks. The problem then asks for the added weight (kN) due to the liquid for the given range of the different tank sizes (diameter). My question is how do you get the added weight; do I just add the different volumes to the specific weight. Thanks for the help.

You probably want to re-upload this in the homework help section where you can formally explain your attempt at a solution etc. You'd be far more likely to receive help

## 1. What is specific weight?

Specific weight, also known as unit weight, is the weight of a material per unit volume. It is typically measured in pounds per cubic foot (lb/ft3) or kilograms per cubic meter (kg/m3).

## 2. How is specific weight different from density?

Specific weight and density are closely related, but they are not the same. Density is the mass of a material per unit volume, while specific weight is the weight of a material per unit volume. Density is typically measured in units such as grams per cubic centimeter (g/cm3) or kilograms per cubic meter (kg/m3).

## 3. What factors affect the specific weight of a material?

The specific weight of a material is affected by its composition, temperature, and pressure. For example, the specific weight of water increases with increasing temperature, but decreases with increasing pressure.

## 4. How is specific weight used in engineering and science?

Specific weight is used in engineering and science to calculate the weight of a material based on its volume. This information is important in designing structures and analyzing the behavior of materials under different conditions.

## 5. How do you convert between specific weight and density?

To convert from specific weight to density, divide the specific weight by the acceleration due to gravity (9.81 m/s2 or 32.2 ft/s2). To convert from density to specific weight, multiply the density by the acceleration due to gravity. Make sure to use consistent units for both parameters.
