Answer / 7207502748

Examining the following factors should allow for a reasonable evaluation of cooling towers:
1) Purchased cost
2) Installed cost
3) Fan energy consumption
4) Pump energy consumption
5) Water use
6) Water treatment costs
7) Expected maintenance costs
8) Worker safety requirements
9) Environmental safety
10) Expected service life

Answer / 7207502748

Evaluating cooling tower bids should be compared following Factors-

* Fan energy consumption

* Pump energy consumption

* Purchased cost

* Installed cost

* Water treatment costs

* maintenance costs

* safety measurements

* Environmental conditions

Question 106 - In a wavefunction, let P(x) = A cos kx + B sin kx. By using the boundary conditions of x = 0 and x = l, where P(0) = P(l) = 0, prove by mathematical calculation that P(x) = B sin (npx / l) where p = 22 / 7 approximately, n is a rounded number. A, B and k are constants.

MICROBIOLOGICAL ENGINEERING - QUESTION 28.3 : In the calculation of the growth of bacteria, absorbance, A in spectrophotometry is used. According to Beer-Lambert Law, A = e x l x c where A is the absorbance of the solution (no unit), l is the distance of light travels through the solution (in cm), e is the molar absorptivity or the molar extinction coefficient [ in L / (mol.cm) ]. For a particular solute and fixed path length : As / Ao = Cs / Co where Ao is the observed signal for a known concentration Co, and As is the observed signal for a sample concentration Cs. (a) For a cell concentration of 560 cells / mL, a spectrophotometre gives an absorbance reading of 1.0. A mixture of concentration 3600000 cells / mL can be diluted in several operations, with each operation having a dilution of 1:20. How many dilutions should be made so that the concentration of this mixture can be calculated within a range of A = 0.0 to 1.0. (b) In another experiment, a sample tube of 1 cm in width is used. Let A = 0.06 and e = 0.0012 ml / (cell.cm). Find the cell concentration of the sample.
