(a)
Interpretation:
It should be determined that how many independent material balance may be written for this system.
Concept introduction:
The independent material balance is when the stoichiometric equation of anyone of them can not be obtained by adding or subtracting multiples of the stoichiometric equation of the others.
The material balances are non independent; if two molecular species are in same ratio to each other wherever they appear and if two atomic species are in same ratio to each other wherever they occur.
(b)
Interpretation:
Calculate
Concept introduction:
In order to understand different variables and components of a system, the analysis of degree of freedom can work better. If the degree of freedom is zero then the problem is specified.
The degree of freedom is explained as:
Where, m is total number of independent stream variables, n is number of independent balances, p is total number of specified terms and s is total number of subsidiary relation.
(c)
Interpretation:
Calculate the difference between amount of acetic acid in the feed mixture and that in the 0.5% mixture and show that it equals the amount that leaves in the 9.6% mixture.
Concept introduction:
In any system, for any conserved quantity like total mass, mass of particular species, momentum, energy etc. the balance can be expressed as follows:
Where, input is feed that enters through system boundary, generation is the content produced within system, output is the content which leaves the system and consumption is the feed consumed within the system while accumulation is the actual product build up in the system.
(d)
Interpretation:
Sketch a flow chart of a two-unit process that might be used to recover nearly pure acetic acid from an acetic acid-water mixture.
Concept introduction:
Actually, when a few process information is given and the calculation is to be done on the basis of the information, then in such conditions, flowchart creation is the best way to deal with. It is formed with the help of boxes and arrows to show the process and outline the process units. The arrow lines can show inputs and outputs which help in better understanding of the process.

- and the viscosity of the water is 1.24 × 104 Nsm 2. Answer: Slug flow 1. Determine the range of mean density of a mixture of air in a 50:50 oil-water liquid phase across a range of gas void fractions. The den- sity of oil is 900 kgm³, water is 1000 kgm³, and gas is 10 kgm³.arrow_forwardA chemical reaction takes place in a container of cross-sectional area 50.0 cm2. As a result of the reaction, a piston is pushed out through 15 cm against an external pressure of 121 kPa. Calculate the work done (in J) by the system.arrow_forwardExample 7.2 Steam is generated in a high pressure boiler containing tubes 2.5 m long and 12.5 mm internal diameter. The wall roughness is 0.005 mm. Water enters the tubes at a pressure of 55.05 bar and a temperature of 270°C, and the water flow rate through each tube is 500 kg/h. Each tube is heated uniformly at a rate of 50 kW. Calle (a) Estimate the pressure drop across each tube (neglecting end effects) using (i) the homogeneous flow model and (ii) the Martinelli-Nelson correlation. (b) How should the calculation be modified if the inlet temperature were 230°C at the same pressure?arrow_forward
