Define the following in chemical engineering perspective and draw an arrow block diagram of the following: 1. Absorption 2. Filtration 3. Drying 4. Liquefaction

After filtration, the cake is washed with water whose volume is 5% of the filtrate volume. If it takes 1.5 hours to dismantle, clean, and re-assemble the filter, calculate the time of washing and the capacity of the filter.

Distillation is an essential operation used commonly for the separation of materials in process engineering. Explain clearly how relative volatility can influence separation process by distillation

8) What are the changes in relative density in different stages of sintering?

b) A complete drying experiment for two different materials (sand and minced meat) was conducted in the laboratory. The results of drying rate for both materials are as shown in Figure 3. Compare and explain the drying rate behavior for sand and minced meat. Drying rate Sand Minced meat Drying time Figure 3 Relation between drying rate and drying time

Explain in detail about hydration and setting times of cement

In the dryer models for a belt dryer with throughcirculation and a direct-heat rotary dryer, is the rate of drying based on heat transfer or mass transfer? Why?

Under what drying conditions is the moisture-evaporation temperature equal to the wet-bulb temperature?
