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.

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.
Question 6: Which of the following is NOT true if you are changing into a
turning lane?
You should activate your signals 100 feet beforehand
You should activate your signals when you get into the turn lane
You should activate your signals before you get into the turn lane
You should use your hands to signal if your lights do not work
Answer:
You should activate your signals 100 feet before you turn, becuase of that you should not wait until you are turning to turn on your signals. If you do not have working lights use your hands. So the answer that is inccorect is B.
You should activate your signals when you get into the turn lane is NOT true
Because you are supposed to single beforhand not while you're in the lane.

projection
Answer:
Orthographic projection is a projection method to present three-dimensional shapes in two-dimensional format in which the projection lines are drawn to be orthogonal to the plane of projection, such that each view of the three-dimensional object is translated to a view of the orthographic projection and orthogonal to the view
A multiview projection is the representation of a three-dimensional projection by two or more two-dimensional views

4. Two technicians are discussing the evaporative emission monitor. Technician A says that serious monitor faults cause a blinking malfunction indicator lamp
(MIL) or even an engine shutdown. Technician B says that the engine computer will run the EVAP monitor when fuel level is within 15 to 25 percent and the TP
sensor position is between 9 and 10 percent. Who is correct?
O A. Neither Technician A nor B
O B. Both Technicians A and BN
O C. Technician A
OD. Technician B
Answer:
The correct option is;
Neither Technician A nor B
Explanation:
The evaporative emission monitor or Evaporaive Emission Control System EVAP System monitors enables the Power Control Module of the car to check fuel system leak integrity and the vapor consumption efficiency during engine combustion
It is a requirement of EPA on cars to check the emission of smug forming evaporates from cars
Serious monitor faults can cause the turning on of the check engine lights and the vehicle will not pass OBD II test, but it will not lead to engine shutdown
It runs when the engine is 15 to 85% full and the TP sensor is between 9% and 35%.
Therefore, the correct option is that neither Technician A nor B are correct.

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.

If sail boats A and B are approaching each other with the wind on different sides, why is vessel A considered the give-way vessel (vessel that must take early and substantial action to avoid a collision)?
Answer:
The reason is because when the wind approaches each sailboat from a different side, the sailboat that the wind approaches from the port side, which is the left side is the give-way vessel.
Whereby the wind approaches the vessel A from the port (left) side then vessel A is considered the give-way vessel
The give-way vessel is the vessel that will have to take expeditious steps to create access for the other vessels by either changing course, stopping, or moving with reduced speed
