What is material balance and energy balance?
A material and energy balance is essentially a quantitative account of the redistribution of material and/or energy that occurs when anything happens. This basic tool of process engineering can be used to solve many practical problems.

What is material balance and energy balance?
A material and energy balance is essentially a quantitative account of the redistribution of material and/or energy that occurs when anything happens. This basic tool of process engineering can be used to solve many practical problems.
What is material energy balance explain with example?
Material balances can be based on total mass, mass of dry solids, or mass of particular compo- nents, for example protein. Skim milk is prepared by the removal of some of the fat from whole milk. This skim milk is found to contain 90.5% water, 3.5% protein, 5.1% carbohydrate, 0.1% fat and 0.8% ash.
What do you mean by material balance?
A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
What is material balance principle?
According to the first law of thermodynamics, matter can neither be created nor destroyed; this is known as the Material Balance Principle (MBP). For the first time, in 1969, Ayres and Kneese [15] added this concept to the glossary of economics.
How do you select basis in material balance?
A basis is the flowrate of one stream or component (mix or single component of the mix). If a flow (mass or molar) is given, it is probably a good basis to use. Otherwise assume a basis, perhaps on the stream with the “most known” composition ( so you can immediately calculate the flow of rates of the species).
How does energy balance work?
Energy balance is defined as the state achieved when the energy intake equals energy expenditure. This concept may be used to demonstrate how bodyweight will change over time in response to changes in energy intake and expenditure. When the body is in energy balance, bodyweight is stable.
