1. The problem involves understanding the sieve analysis data for turmeric powder. 2. Sieve analysis is a method to determine the particle size distribution of a powder by passing it through a series of sieves with different mesh sizes. 3. The table shows the mass of turmeric powder retained on each sieve: 20, 35, 60, 80, and the pan (which collects the finest particles). 4. To analyze this data, you calculate the percentage of total mass retained on each sieve by dividing the mass retained on each sieve by the total mass and multiplying by 100. 5. This helps to understand how much of the powder is made up of different particle sizes. 6. The formula $Q = \dot{m} C_p \Delta T$ is unrelated to the sieve analysis; it is used for calculating heat energy in other contexts. 7. In simple terms, question 2 asks you to interpret the sieve data to understand the size distribution of turmeric powder particles.
