QUESTION 1: Different Line Types Look at the drawing of a different bicycle pump below. This drawing is accurate, so we call it a scale draw It is four times smaller than a real pump. We say it is drawn to a scale of 1:4. That means that if you meas the length of the outer tube of this drawing, it will be four times smaller than the outer tube of the real pu F + 320 Figure 9: Bicycle pump. Scale 1:4 Why is the outer tube of this pump drawn with solid lines?
Answers
Answer:
The outer tube of the pump is drawn with solid lines because it represents the visible edges of the object, which are the most important and prominent features of the drawing. Solid lines are used to indicate visible edges, while other types of lines such as dashed or dotted lines are used for hidden or construction lines that are not meant to be seen in the final drawing.
Explanation:
When drawing an object, it's important to distinguish between the visible edges and the hidden or construction lines. The visible edges are the lines that represent the outer contour or silhouette of the object, which define its shape and form. In the case of the bicycle pump, the outer tube is the most prominent and recognizable feature of the pump, so it's drawn with solid lines to emphasize its importance and to make it stand out from the other parts of the pump.
On the other hand, the hidden or construction lines are used to guide the drawing process, to show the internal structure or components of the object, or to indicate the position of other features that are not visible from the current viewpoint. These lines are usually drawn with dashed or dotted lines to distinguish them from the visible edges and to avoid confusion.
By using different types of lines, the artist can create a clear and accurate representation of the object, with all the relevant information conveyed in a concise and understandable way. This is especially important in technical or scientific drawings, where precision and clarity are essential for conveying complex ideas or designs.
A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
Answers
The Answers for the given question are as follow:
a. The model speed is approximately 31.62 rev/min.
b. The scale ratio is approximately 0.0417.
c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.
d. The bearing thrust of the model is approximately 9.72 kN.
To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.
a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:
Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed
= (√4.9/√16.5) * 93.7 rev/min
= 31.62 rev/min
b. The scale ratio can be determined using the equation:
Scale ratio = (√(Model power))/(√(Full-size power))
= (√37.5kW)/(√27MW)
≈ 0.0417
c. To estimate the volume flow rate through the model, we can use the power equation:
Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)
37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)
Solving for the volume flow rate:
Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)
≈ 943.44 m^3/s
d. To calculate the bearing thrust of the model, we can use the principle of force similarity:
Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust
= (37.5kW / 27MW) * 7.0GN
≈ 9.72kN

Answers
Answer:
C - 4/5
Explanation:
2 nearly out of five teens have tried alcohol is 40%. Option C
How to determine the valueThe statement "2 out of 5 teens have tried alcohol" can be translated into a mathematical calculation as follows:
Percentage of teens who have tried alcohol = (Number who have tried alcohol / Total number of teens) * 100
Given that "2 out of 5" teens have tried alcohol, this means:
Number who have tried alcohol = 2
Total number of teens = 5
So, the calculation would be:
Percentage = (2 / 5) × 100
= 40%

Technician a says that when more air is entering a spray booth than is removed it is considered to have negative pressure technician b say the negative air pressure draws more overspray through spray booth filters than positive air pressure Who’s right
Answers
In a spray booth, when the amount of air entering the booth is greater than the amount of air being removed, it is considered to have positive pressure. Conversely, when the amount of air being removed is greater than the amount of air entering, it is considered to have negative pressure. Therefore, Technician A's statement is incorrect.
On the other hand, Technician B's statement is correct. Negative air pressure can draw more overspray through spray booth filters because it creates a vacuum effect that draws in the overspray and helps prevent it from escaping into the rest of the work area. This is why spray booths are designed to have a negative pressure differential to help control overspray and keep the work environment safe.
Technician A is correct in stating that when more air is entering the spray booth than is being removed, it is considered to have negative pressure. Negative pressure means that the pressure inside the spray booth is lower than the pressure outside. This setup helps to contain the overspray and fumes within the booth, minimizing the risk of spreading them to the surrounding areas.
Technician B is also correct in stating that negative air pressure draws more overspray through the spray booth filters than positive air pressure. When the spray booth has negative pressure, it creates a suction effect. This suction draws the overspray particles towards the filters, improving their efficiency in capturing and removing the overspray from the air.
In summary, both technicians are correct in their statements. The negative pressure in the spray booth helps contain the overspray, and it also enhances the effectiveness of the booth's filters in capturing the overspray particles.
