Weight Retained in Sieve Calculator

Introduction

Sieve analysis is a common method used to determine the particle size distribution of a granular material. It involves passing a sample of the material through a series of sieves with progressively smaller openings. The Weight Retained in Sieve Calculator helps determine the weight of particles that are retained on each sieve, providing valuable data for particle size characterization.

Formula:

The Weight Retained in Sieve Calculator calculates the weight of particles retained on a sieve based on the initial weight of the sieve and its contents before sieving ( $W_{initial}$ , in grams), and the weight of the sieve and its contents after sieving ( $W_{final}$ , in grams). The formula for calculating the weight retained in a sieve ( $W_{retained}$ , in grams) is as follows:

$W_{retained} = W_{initial} - W_{final}$

Where:

$W_{retained}$ is the weight of particles retained on the sieve.
$W_{initial}$ is the initial weight of the sieve and its contents.
$W_{final}$ is the weight of the sieve and its contents after sieving.

This formula enables users to determine the weight of particles of a specific size range within the material being analyzed.

How to Use?

To effectively use the Weight Retained in Sieve Calculator for particle size analysis, follow these steps:

Prepare the Sieves: Set up the series of sieves with progressively smaller openings, starting with the coarsest sieve on top.
Weigh the Sieve and Material: Weigh the initial weight ( $W_{initial}$ ) of the sieve and its contents. Ensure that the weight is measured in grams.
Perform Sieving: Pass the material through the sieves using a mechanical or manual sieving process.
Weigh the Sieve and Retained Material: After sieving, weigh the sieve and the material that remains on it. Record this weight as $W_{final}$ in grams.
Apply the Formula: Input the values of $W_{initial}$ and $W_{final}$ into the Weight Retained in Sieve Calculator formula:
$W_{retained} = W_{initial} - W_{final}$
Calculate Weight Retained: Execute the calculation to obtain the weight of particles retained on the sieve ( $W_{retained}$ ).
Repeat for Other Sieves: If you are conducting a complete particle size analysis, repeat the process for each sieve in the series.

Example:

Let’s illustrate the use of the Weight Retained in Sieve Calculator with a practical example:

Suppose you are performing a sieve analysis of a soil sample. You initially weigh the sieve and its contents ( $W_{initial}$ ) and find it to be 250 grams. After sieving, you weigh the sieve and the retained material ( $W_{final}$ ) and find it to be 120 grams.

Using the formula:

$W_{retained} = 250 grams - 120 grams$

$W_{retained} = 130 grams$

The weight of particles retained on the sieve is 130 grams.
