Answer / amit

1.It is easy to take side stream for intermediate heating and cooling in case of from tray column compare to packed column.
2.in case of packed column some times channeling of liquid stream occurs so to prevent it tray column cab be preffered.

Answer / mani

1.the selection of type of column is based on man design
constrains
2. if dia of column is less than 0.6 m packed bed is preffered
and it gives low pressure drop, high liquid hold up
3. tray column gives high pressure drop and suitable for dia
more than 0.6m

Answer / rajesh

no its not like that we can use any one of the column
depending upon our recruitment
because both are having the advantages and disadvantages
so if u need exactly why u need to specify teh exact
question

Answer / abhijit

Becoz of high pressur drop in packed columns.

Answer / bala

packed column only give high pressure drop and tray column is preferred because of its easy inspection and maintenance

ENVIRONMENTAL ENGINEERING - QUESTION 22.2 : Biochemical Oxygen Demand (BOD) could be calculated using the formula BOD = (DOi - DOf) (Vb / Vs) where Vb = Volume of bottle in ml, Vs = Volume of sample in ml, DOi = Initial dissolved oxygen in mg / L, DOf = Final dissolved oxygen in mg / L. (a) By using a bottle of Vb = 300 ml with sample Vs = 30 ml, find the BOD if DOi = 8.8 mg / L and DOf = 5.9 mg / L. (b) By using a bottle Vb = 600 mL with sample Vs = 100 mL, find the BOD if DOi = 8.8 mg / L and DOf = 4.2 mg / L. (c) Find the average BOD = [ Answer of (a) + Answer of (b) ] / 2. (d) If the BOD-5 test for (a) - (c) is run on a secondary effluent using a nitrification inhibitor, find the nitrogenous BOD (NBOD) = TBOD - CBOD. Let TBOD = 45 mg / L and CBOD = Answer of (c).

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.20 : Assume an engineer buys a $1 bond in period T while the nominal interest rate is R. The inflation rate at T + 1 is anticipated to be I. (a) If the bond is redeemed in period T + 1, how much money will the buyer engineer receive, in term of R, which is not affected by inflation? (b) Find the present value, PV of the proceeds from the bond, in term of R and I. (c) If the bond is redeemed in period T + 1, calculate the real growth or real value of the money that the buyer engineer will receive, in term of r = real interest rate, which is affected by inflation. (d) From the answers in (b) and (c), find the values of x, y and z in the following Fisher equation : (1 + x) = (1 + y) / (1 + z), in term of r, R and I.
