**Divide the masses for each sieve (individual/cumulative) by the total dry mass before washing and multiply by 100 to determine the percent retained on and passing each sieve.**

## How to Calculate Percentage Passing in Sieve Analysis?

Sieve analysis is an important part of calculating the percentage of particles passing through a given sieve size. This process is also known as particle size analysis or grain size analysis. It is used to determine the size distribution of particles in a sample by passing the sample through a series of sieves.

The sieves are usually stacked on top of each other, with the smallest size at the top and the largest at the bottom. The particles that pass through the sieve are collected while the particles that remain on the sieve are weighed. The results of the sieve analysis are used to calculate the percentage of particles that pass through each sieve size.

The process of calculating the percentage of particles passing through a sieve size is relatively simple. First, the weight of the sample is determined. Second, the weight of the particles that passed through the sieve is determined. Third, the weight of the particles that remained on the sieve is determined. Finally, the percentage of particles passing through the sieve is calculated by dividing the weight of the particles that passed through the sieve by the total weight of the sample.

For example, if the weight of the sample is 1,000g and the weight of the particles that passed through the sieve
