Answer / dhaval modh
unit operation means the operation in which only physical
change occur not chemical.ex.fluid operation,mechanical
operation,heat tranfer operation, mass tranfer
operation.ie.distillation,drying,adsorption etc......

Answer / darshan jagatap
MAIN CHARACTERISTICS OF UNIT OPERATIONS IS THERE IS ONLY
PHYSICAL CHANGE (PHASE CHANGE) AND NO REACTIONS
CHARACTERISTICS:
PHASE CHANGE IS TOBE OBTAINED BY MAINTAING THE PARAMETERS
SUCH AS TEMP, PRESSURE, FLOW, LEVEL ETC

Answer / alok kumar
basically fluid machanics ,heat transfer operation operation
,mass transfer comes in catagory of unit operations.
the basic thing is that during 1 or more unit operations
there is no chemical composition change occur only physical
changes such as temp. etc. change.

BIOPROCESS ENGINEERING - EXAMPLE 14.1 : In differential centrifugation of cells with diameter D in centimeter, the square of D is given by D x D = [18n ln (RF / RI) ] / [ (RP - RFF) Wt ] where n is the fluid viscosity (poise), RF is the final radius of rotation (cm), RI is the initial radius of rotation (cm), RP is cell density (g / ml), RFF is the fluid density (g/ml), W the square for the rotational velocity in (radians / s) (radians / s), t is the time required to sediment from RI to RF (s). Derive an equation for W as a function for D, n, RF, RI, RP, RFF and t, with the stated units above, in radian & degree.
my qualification is b.tech- industrial biotech. i was read about many chemical engineering subject as a allied like unit operation, chemical thermodynamics, chemical reaction engineering , mass transfer and separation, downstream processing and principle of chemical engineering. and i have 2 yrs working exprience on in the field of instrumentation and control... and my query is "can i able work as process technologist" and which subject i want conc. more?........
Question 75 - The molecular weights M in kg / mol of 3 different monomers a, b and c in a polymer are Ma = 14, Mb = 16 and Mc = 18. The fraction of polymer chain X of 3 different monomers a, b and c in a polymer are Xa = 0.5, Xb = 0.3 and Xc = 0.2. (i) Calculate number average molecular weight by using the formula Ma Xa + Mb Xb + Mc Xc. (ii) Calculate weight average molecular weight by using the formula (Ma Xa Ma + Mb Xb Mb + Mc Xc Mc) / (Ma Xa + Mb Xb + Mc Xc). (iii) Calculate the polydispersity by using the answer in (ii) divided by answer in (i). (iv) If the molecular weight of repeat unit is 12, calculate the degree of polymerization by using the formula (Ma Xa + Mb Xb + Mc Xc) / (molecular weight of repeat unit).
Can any one send me the sample test papers of IOCL entry exam to be held on 6th july 2008. Also plz send the interview questions that cud probably be asked........i wud be highly obliged if u can send a few test paers and other stuff @ inderjeetd@gmail.com.........Inderpreet
Input the Roll Number, Name and marks of a small section of 5 students. Display the marks database of these students in the following format. The "Roll Number" and "Name" fields are left justified with 15 columns, and 25 columns, respectively. The "Marks" field is right justified with 5 columns. Assume the marks are in multiples of 0.5 and are from 0 to 100. Display some spaces between each field appropriately.
