The energy balance is very important in chemical engineering. In this case of the thinking and the case that depends upon the very different energy balance equation and in that case, they need to follow the different phase and then they process the differential equation in that case they need to follow some of their different sequential and the differential equation. In this part, the major part is the energy balance and the second part is multiphase so that is the where used in the differential equation. On the other hand the energy balances equation and the multiphase sampling theorem.

**Definition of Energy Balance**

The energy balance is the consideration of the energy input and the energy output and therefore the consumption of the generation in the process and the stage. Therefore the presence in the data and the energy common unit in the phase that is all about the balance and thinking and the case of the equation and in that case that is all about the specific information in the data and the equation that is all about the equation. In this part, the major part is the energy balance and the second part is multiphase so that is the where used in the differential equation. Therefore the energy balance is all about the thinking, the sense of the energy input, and the energy output.

**Use of Energy Balance Equation **

The energy balance equation is the equation that they have to find that the energy balance is equal to the energy input- energy output. The energy balance equation is stated as chemical engineering and in this case, the energy balance and the equation are all about the thinking and in terms of the thinking and the strategy and therefore theory needs to protect from the balancing equation. . In multistage sampling or cluster, sampling population gathered data is divided into smaller formulas or in smaller groups to create a mathematical formula to solve out their different ratios by using several steps. A better example of this is hierarchical groups that mainly focus on division in small forms such as from state to city to neighborhoods to create a better sample that is less expensive and less time-consuming in data collection. The energy balance equation is, in that case, they have to provide some equation and in the case, they follow them in that is all about the specific information in the data and the equation that is all about the equation. The energy balance equation and in that case they need to follow the sampling and the term that is all about the equation on the energy sampling. On the other hand the balancing equation and the information that is all about the energy balance equation and in that case that is all about the multiphase sampling.

**Use of Multiphase Sampling**** **

Multiphase or cluster sampling is used to collect data by drawing a sample formation from a division in different groups. At each stage, this sampling is used to collect data from a gathered form and geographically distributed among different speeded groups based on national surveys. Modern sampling formulation or multistage data collection method is far better and better than single-stage sampling. As per the nationwide population data survey, in single-stage data collection, the population is divided into units according to daily people’s growth such as household things or on an individual basis. In multistage sampling or cluster, the sampling population gathered data is divided into smaller formulas or in smaller groups to create a mathematical formula to solve their different ratios by using several steps. A better example of this is hierarchical groups that mainly focus on division in small forms such as from state to city to neighborhoods to create a better sample that is less expensive and less time-consuming in data collection. Moreover observed data is a cluster or multi-stage sampling is more satisfying, mutually exclusive, and exhaustive. Cluster formulation is the basic principle of this strategy: geographical location (cities or states), organizational structure (for example schools or colleges) is randomly calculated of their households according to multistage data sampling.

**Conclusion**** **

In this section, it can be concluded that the in the energy balance equation and the in the case of therefore the some of the equation and the part and the thinking is all about the thinking and the case that is all about the thinking and the energy balance equation. In that case, they have to follow some of the energy balance equation and the terms that are also the phase and therefore it can be said that in that case that the section is the sampling methods.
