A solute A is being absorbed from a binary gas mixture of A and C into a pure solvent B in a packed tower with a cross sectional area of 0.2 m² at a temperature of 300 K and pressure of 1 atm. The inlet gas contains 3 mol% of A and its desired to remove 85% percent of A from the gas stream. The feed gas flowrate is 14 kmol/h and the solvent flowrate is 45 kmol/h. k_y’a_h = 0.04 kmol/m³s and k_x’a_h = 0.06 kmol/m³s. The equilibrium relationship can be assumed y = 1.2x.

What is the packing tower height?

130 kg of uniform spherical particles with a diameter of 60 mm and particle density 1500 kg/m³ are fludised by water (density 1000 kg/m³, viscosity 0.001 Pa s) in a circular bed of cross-sectional area 0.2 m². The single particle terminal velocity of the particles is 0.98 mm/s and the voidage at incipient fludisation is known to be 0.47. Determine:

The minimum fludised velocity and the bed height at incipient fludisation.                               

The mean fludised bed voidage and height when the liquid flow rate is 2x10^-5 m³/s.  

Consider the following.

a. What is the duration of a two-year bond that pays an annual coupon of 9 percent and whose current yield to maturity is 14 percent? Use $1,000 as the face value. (Do not round intermediate calculations. Round your answer to 3 decimal places. (e.g., 32.161))
b. What is the expected change in the price of the bond if interest rates are expected to decrease by 0.2 percent? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places. (e.g., 32.16))

Standard deviation of the portfolio with stock A is _%?

Standard deviation of the portfolio with stock B is _%?

C++ EXERCISES

(a) Given int a = 5, b = 2, c = 4, and d = 5; determine the value of the expression:

d % b * c > 5 || c % b * d < 7.   

(b) Which repetition statement is preferred for user data input and its validation?             

(c) Write a for statement to populate an array, double val[NUMCOUNT], for the following case: Use a counter named double count that has an initial value of 16.2, a final value of 0.4, and a decrement of 0.2 and populate the val[] array with the value of count.

What is the size, NUMCOUNT, of the array val[]?

You are a marketing manager for apple and decision has been made that they will begin selling custom-built premium gaming device.
