Suppose you have an electrostatic precipitator currently
operating at 90% for 3 µm diameter particles and you need to
increase the efficiency to 98% to comply with your operating
permit.
a. Using the Deutsch equation, identify three parameters you
could change in order to increase your efficiency. By what
percentage would you have to change each separately to achieve your
goal?
b. Suppose that you decide simply to add a cyclone in series
with the ESP in order to reduce the PM concentration in the flue
gas, rather than changing the ESP parameters as in part a. What
must the control efficiency of the cyclone be in order for the
combined control efficiency to be 98%?
c. For most of the course we have assumed PM as solid,
spherical particles with a density of 2200 kg/m3. Suppose our
control system must capture particles of zinc with a density of
7140 kg/m3. How much will this alteration increase or decrease the
efficiency of our combined ESP-cyclone system?

A certain stainless steel powder is supposed to have a mean
particle diameter of 19 µm. A random sample of 87 particles had a
mean diameter of 19.4 µm. It is known that the population has a
standard deviation of 1.8 µm. Is there evidence that the mean
particle diameter is not 19?
(a) State the appropriate null and alternative hypotheses.
(b) Compute the test statistic.
(c) Compute the p-value.
(e) Does the 90% confidence interval contain 19? Explain

Q. Spherical glass particles (12 mm diameter and 2500 kg/m 3
density) and spherical metal particles (1.5 mm diameter and 7500
kg/m3) are falling in water (density= 1000 kg/m3) .
(1) Calculate the terminal falling velocities of glass and metal
particles in water for a constant friction factor of 0.22.
(2) At what water velocity will fluidized beds of glass
particles and metal particles have the same bed densities?
The relation between fluidization velocity (uc),
terminal velocity (ut) and bed...

Your firm currently has an operating cycle of 90 days. You are
analyzing some operational changes which are expected to decrease
the accounts receivable period by 4 days and decrease the inventory
period by 5 days. The accounts payable turnover rate is expected to
increase from 8 to 9 times per year. If all of these changes are
adopted, what will be your firm's new cash cycle?
a) 46 days
b) 41 days
c) 51 days
d) 72 days

Suppose the Xenon (XO) currently is selling at $90 per share.
You buy 300 shares, using $20,000 of your own money, and borrow the
remainder of the purchase price from your
broker. The rate on the margin loan is 6 percent.
a. What is the percentage increase in the net wealth of your
brokerage account if the price of XO immediately changes to
(1)$98
(2)$90
(3)$82
What is the relationship between your percentage return and the
percentage change in the...

Suppose that you sell short 300 shares of CYSCO (CY), currently
selling for $90 per share, and give your broker $20,000 to
establish your margin account.
a. If you earn no interest on the funds in your margin account,
what will be your rate of return after one year if CY stock is
selling at $98? Assume that CY pays no dividends.
b. If the minimum margin is 30 percent, how high can CY’s price
