Emerald® Designer EditionTM is Sherwin Williams’ “finest interior architectural coating” (or, more commonly, paint). Drying time is stated to be temperature and humidity dependent: for recoating: 4 hours, assuming 77o F and 50% relative humidity.
A contractor records relative humidity and drying time for ten recent jobs as shown at right.

A liquid food(viscosty: 0.003 Pa S; density:1033 kg/m^3) is being pumped at a rate of 3 m^3/h from a tank A, where the absolute pressure is 12,350 Pa, to a tank B, where the absolute pressure is 101,325 Pa, through a sanitary with 3.8 cm diameter and 4.6x10^-5 m surface roughness. The pump is 1 m below the liquid level in tank A and the discharge in tank B is 3.3 m above the pump. If the length of the pipe in the suction line is 2 m, the dischargeline 10 m, and there are one 90 degree anlge flanged elbow in the suction line, two 90 degree angle thread elbowsin the discharge line, and one globe valve in the discharge line. Calculate he pump power required for finishing this job, assuming the efficeincy of the pump is 65%.

8.21 Program: Convert to binary. Sections 2.7, 3.8, 5.2. Functions.
Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:
As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2
Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string.
Your program must define and call the following two functions.
The function integer_to_reverse_binary() should return a string of
1's and 0's representing the integer in binary (in reverse). The
function reverse_string() should return a string representing the
input string in reverse.
def integer_to_reverse_binary(integer_value)
def reverse_string(input_string)
Ex: If the input is:
6
the output is:
110

An article in Solid State Technology, "Orthogonal design for
process optimization and its application to plasma etching" by
G.Z.Yin and D.W.
Jillie (May, 1987) describes an experiment to determine the effect
of the
C2F6 flow rate on the uniformity of the etch on a silicon wafer
used in
integrated circuit manufacturing. All of the runs were made in
random order. Data for two flow rates are as follows:
C2F6 Uniformity Observation
Flow 1
2 3
4 5 6
125 2.7 4.6 2.6 3.0 3.2 3.8
200 4.6 3.4 2.9 3.5 4.1 5.1
a) Does C2F6 flow rate affect average etch uniformity? use a=0.05
b) What is the P-value for the test in part (a)
c)Does the C2F6 affect the wafer-to-wafer variability in each uniformity? use a0.05
d) Draw box plots to assist in the interpretation of the data from this experiment

| IRR ($) | 12 | 14 |
| MIRR (%) | 10 | 11 |
| PI | 1.2 | 1.5 |
| Payback Period (years) | 3 | 3.8 |
| Discounted Payback Pd (Years) | 4.2 | 4.8 |
Nokia's cost of capital is 8%. Its critical payback period is 2 years and the critical discount payback period is 3 years
NPV - (Project A be accepted, Project B be accepted, or neither)
IRR - (Project A be accepted, Project B be accepted, or neither)
MIRR - (Project A be accepted, Project B be accepted, or neither)
PI - (Project A be accepted, Project B be accepted, or neither)
Payback pd - (Project A be accepted, Project B be accepted, or neither)

Andrea would like to organize SHO as either an LLC (taxed as a sole proprietorship) or a C corporation. In either form, the entity is expected to generate an 12 percent annual before-tax return on a $920,000 investment. Andrea’s marginal income tax rate is 35 percent and her tax rate on dividends and capital gains is 15 percent. Andrea will also pay a 3.8 percent net investment income tax on dividends and capital gains she recognizes. If Andrea organizes SHO as an LLC, Andrea will be required to pay an additional 2.9 percent for self-employment tax and an additional 0.9 percent for the additional Medicare tax. Further, she is eligible to claim the full deduction for qualified business income. Assume that SHO will pay out all of its after-tax earnings every year as a dividend if it is formed as a C corporation.
