Improve Your Writing
You may need to improve your ability to express yourself in writing.
To some degree, most organisations rely on the accurate transfer of information and that calls for the accurate use of language. When speaking, most people make multiple errors of grammar and vocabulary, and nobody seems to mind. But when you are doing business at work, then the business agreement is usually in the form of a written document; and that document has to be worded properly.
How would you rate your ability to express yourself properly in writing? Are you a good writer or do you lack knowledge of grammar, punctuation, logic and rhetoric?
If you are not as good at writing as you need to be, then study grammar, study punctuation, logic and rhetoric.
Start by buying a copy of a book called 'Rex Barks' by Phyllis Davenport.
This book is the gateway to grammar - and Phyllis is phenomenal.

Atmospheric air at 1 atm has a dry-bulb temperature of 20°C and a wet-bulb temperature of 15°C. Determine the dew point temperature
Answer:
The dew point temperature is 11.65°C
Explanation:
Dew point temperature formula is given as follows;
From the modified Apjohn equation, we have;
[tex]P_v = P'_v -\dfrac{1.8 \times p (t - t')}{2700}[/tex]
Which gives;
The saturation vapor pressure at 15°C = 1.705 kPa
[tex]P'_v[/tex] = 1.705 kPa
p = 101.325 kPa
[tex]P_v[/tex] = 1.705 - 1.8*101.325*(20 - 15)/2700 = 1.36725 kPa
The dew point temperature is the steam saturation temperature at 1.36725 kPa
= 6.9696 + (17.4953 - 6.9696)*(0.0136725 - 0.01)/(0.02 - 0.01) = 10.84°C by approximation calculation from steam tables and 284.8 K = 11.65°C from Wolfram Alpha.

3. An underground copper pipe is used to transport oil under a factory. It is very important that this pipe does not oxidize, so engineers use impressed current cathodic protection. a. Would zinc be an appropriate metal to use for cathodic protection? Why or why not? (4 points) b. Engineers attach a sacrificial anode to the copper pipe. To use impressed current cathodic protection, they must attach a battery between the cathode and anode. Which material should the positive side of the battery be attached to? Explain how you know. (4 points)
Answer:
a) Copper corrosion is prevented by an external current source that provides a condition around the copper that halts the rust through current cathodic protection
Due to the location of the pipeline, an material such as graphite, titanium, or niobium can be used which lasts longer that zinc can be used for longevity of the protection
b) The positive side of the output DC terminals are attached to the anodes such as graphite, while the negative terminals are connected to the copper pipe to be protected
Explanation:
Making the protected metal the cathode will make the metal be the source of electrons into the reaction taking place such that the release of the positive metal ions that results in disintegration takes place at the anode and as such the protected metal made the cathode, to which the negative terminal of the battery is attached is protected.
If you think a hazard is serious, what is the best way to ensure that OSHA will
conduct a site inspection?
Help
Answer:
The best way to ensure that OSHA will conduct a site inspection is by the submission a signed (by a current employee or employee representative) Formal Written complaints following OSHA guidelines (which can be found in the Council of Safety and Health (COSH) website) which will enable the commencement of process for an on site inspection
As such it is advisable to go through the following procedure before, filing a complaint
1) Talk to your workers union about the hazard
2) If you do not belong to a union, talk to your co-workers
3) Inform your employer who has responsibility for on the job safety
4) Speak or have a meeting with OSHA so as to receive guidance before filing a complaint
Explanation:
If you think a hazard is serious, the best way to ensure that OSHA will conduct a site inspection is to file a complaint.
Hazard simply means a potential source of harm. It should be noted that hazards can have detrimental effect on the health of an individual.
If you think a hazard is serious, the best way to ensure that OSHA will conduct a site inspection is to file a complaint asking OSHA to inspect the workplace. In a situation whereby OSHA finds a serious hazard, it'll be kept confidential.

Answer and Explanation:
The answer is the left lane on the far left of the street you our turning onto, when doing a left turn into it.
This is done for if someone on the road is turning right onto the same road you are turning to, in which they would take the right lane on the far right.

Steam enters an adiabatic turbine at 8 MPa and 500 C with a mass flow rate of 3 kg/s andleaves at 30 kPa.The isentropic efficiency of the turbine is 0.90. Neglecting the kinetic energy change of the steam, determine (a) the tem-perature at the turbine exit and (b) the power output of theturbine
Answer:
(a) The exit temperature = 69.1°C
(b) The power output = 8.3 MW
Explanation:
(a) The enthalpy of steam at 8 MPa and 500°C is given (from online sources) as h₁ = 3399 kJ/kg
The exit temperature = The saturation temperature at 30 kPa = T₄ = 69.096 + 273.15 = 342.246 K
The exit temperature = 69.1°C
(b) The mass flow rate = 3 kg/s
The isentropic efficiency = 0.9 = (h₁ - h₂)/(h₁ - h₂[tex]_s[/tex])
s₁ = 6.727 kJ/kgK
h₂[tex]_s[/tex] = 289.229+ 2335.32* (6.8235 - 6.727 )/6.8235 = 322.26 kJ/kg
Therefore, h₂ = h₁ - (h₁ - h₂[tex]_s[/tex])*0.9
h₂ = 3399 - (3399 - 322.26 )*0.9 = 629.934 kJ/kg
The power output = [tex]\dot m[/tex](h₁ - h₂) = 3 *(3399 - 629.934) = 8307.2 kJ/s =
8.3 MW.
