initial amount of A n B in the total mixture. How much kg of A and B was added in the mixtureChestermiller said:In terms of A and B, what is the total mass of the final mixture?
In terms of A and B, what is the mass of solids in the final mixture?

Answers for this question is, A = 1260 kg, B = 872 kgChestermiller said:In terms of A and B, what is the total mass of the final mixture?

I have no idea what you are saying here. Can you please answer the questions I asked (in the form of equations).nahian taskin said:initial amount of A n B in the total mixture. How much kg of A and B was added in the mixture
No equations are given. From this, We have to make our own equation to get the solution.Chestermiller said:I have no idea what you are saying here. Can you please answer the questions I asked (in the form of equations).

how many equations it can be here, that's the confusion because i don't know wether its a batch process or rate process.nahian taskin said:No equations are given. From this, We have to make our own equation to get the solution.
I have tried with this equation:
For solid : 0.05A+ 0.11B = 18.5+ 2150(0.08125)
For Water: 0.95A+ 0.89B = 2150(0.9175)
solve the equations.
but i wrong answer,which means something is wrong in my equation
Batch process : total input = total output.nahian taskin said:how many equations it can be here, that's the confusion because i don't know wether its a batch process or rate process.
This is what I was looking for. Your formulation is very close to being correct. There are just a couple of minor errors.nahian taskin said:No equations are given. From this, We have to make our own equation to get the solution.

if 8.25% is solid then (100-8.25)% is water which is 91.75%Chestermiller said:This is what I was looking for. Your formulation is very close to being correct. There are just a couple of minor errors.
1. In the solid equation, are you sure that 18.5 belongs on the right hand side of the equation?
2. In the water equation, recheck that 0.9175. There's an arithmetic error.
Chet
in the first equation i made a mistake it is 2150(0.0825) not 0.08125nahian taskin said:if 8.25% is solid then (100-8.25)% is water which is 91.75%
and i tried by giving 18.5 on the left hand side, but answer didnt came. It was more far than the actual answer.
nahian taskin said:in the first equation i made a mistake it is 2150(0.0825) not 0.08125
No, i didnt. I am now trying with by corrcting that value in the equationChestermiller said:I know. I just noticed that. Do you get the right answer now with the 18.5 on the left?
Chet
Didnt came again :( with this value .nahian taskin said:No, i didnt. I am now trying with by corrcting that value in the equation
Ohk, thank you :)Chestermiller said:Here are the equations I solved, and I got the correct answer:
For solid : 0.05A+ 0.11B + 18.5 = 2150(0.0825)
For Water: 0.95A+ 0.89B = 2150(0.9175)
If you didn't get the correct answer using these equations, then you need to check your algebra.

A material balance problem is a type of mathematical problem that is commonly encountered in various scientific fields, such as chemistry, physics, and engineering. It involves determining the amount of a substance or component in a system by considering the inputs, outputs, and accumulation of that substance within the system.
Material balance is important because it allows scientists to understand and quantify the changes in a system over time. By using material balance equations, scientists can track the movement of substances within a system and make predictions about future behavior. This is crucial for many industrial processes, environmental studies, and other scientific investigations.
There are several key assumptions made in material balance calculations, including the assumption of a closed system (no inputs or outputs), the assumption of steady-state conditions (no changes in the system over time), and the assumption of conservation of mass (the total mass of the system remains constant).
Material balance is used in a wide range of real-world applications, including chemical process design, environmental pollution monitoring, and oil and gas production. It is also used in various research studies to understand the behavior of natural systems and to develop new technologies.
Solving material balance problems can be challenging due to the complexity of the systems involved and the various assumptions that need to be made. The accuracy of the results also depends on the accuracy of the input data, which can be difficult to obtain in some cases. Additionally, material balance problems may involve multiple variables and equations, making them time-consuming to solve by hand.
