Explanation:

The most commonly installed type of fire sprinkler system is the wet-pipe system. In a wet-pipe system, the pipes are filled with water and are pressurized so that when the heat of a fire activates the sprinkler head, water is released onto the fire.

Pre-action systems use a separate water line to fill the pipes with water and need to be triggered by another type of detector such as smoke or heat, while dry-pipe systems have pressurized air or nitrogen in the pipes and the water is released when the heat of a fire activates the sprinkler head. Deluge systems are used when large amounts of water need to be released quickly, such as when a large area needs to be flooded quickly.

In order to install a wet-pipe system, the pipes must be connected to a water source and the sprinkler heads must be placed at the correct height in the room. Once the system is installed, it must be tested regularly to make sure that it is functioning properly. It is also important to remember that water damage can be caused by a malfunctioning system, so it is important to regularly check and maintain the system.

(a) The probability of drawing a black fuse from the second toolbox is 4/7.

(b) The probability of drawing a white fuse from the second toolbox is 3/7.

(c) The probability that one fuse is white is 27/49.

To calculate the probabilities, we need to consider the number of white and black fuses in each toolbox.

First, let's determine the total number of fuses in each toolbox:

First Toolbox:

Total fuses = 4 white fuses + 3 black fuses = 7 fuses

Second Toolbox:

Total fuses = 3 white fuses + 5 black fuses = 8 fuses

(a) The probability that the fuse drawn from the second toolbox is black:

The probability of drawing a black fuse from the second toolbox depends on the fuse selected from the first toolbox. There are two scenarios to consider:

Scenario 1: The fuse selected from the first toolbox is black.

In this case, the second toolbox will have 3 black fuses remaining out of the total 7 fuses.

Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)

Probability = 3/7

Scenario 2: The fuse selected from the first toolbox is white.

In this case, the second toolbox will have 5 black fuses out of the total 7 fuses.

Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)

Probability = 5/7

To calculate the overall probability, we need to consider the probability of each scenario and weigh it by the probability of selecting a fuse of that color from the first toolbox. Since the fuse from the first toolbox has an equal chance of being white or black, we need to take an average of the probabilities in both scenarios.

Probability of drawing a black fuse from the second toolbox = (Probability of scenario 1 + Probability of scenario 2)/2

Probability of drawing a black fuse from the second toolbox = (3/7 + 5/7)/2

Probability of drawing a black fuse from the second toolbox = 8/14

Probability of drawing a black fuse from the second toolbox = 4/7

Therefore, the probability of drawing a black fuse from the second toolbox is 4/7.

(b) The probability that the fuse drawn from the second toolbox is white:

Similarly, we can calculate the probability of drawing a white fuse from the second toolbox. It will be the complement of the probability of drawing a black fuse.

Probability of drawing a white fuse from the second toolbox = 1 - Probability of drawing a black fuse from the second toolbox

Probability of drawing a white fuse from the second toolbox = 1 - 4/7

Probability of drawing a white fuse from the second toolbox = 3/7

Therefore, the probability of drawing a white fuse from the second toolbox is 3/7.

(c) The probability that one is white:

To calculate the probability that one fuse is white, we need to consider both scenarios: either the fuse drawn from the first toolbox is white and the fuse drawn from the second toolbox is black, or the fuse drawn from the first toolbox is black and the fuse drawn from the second toolbox is white.

Scenario 1: Fuse drawn from the first toolbox is white, and the second toolbox has a black fuse:

Probability = (Probability of drawing a white fuse from the first toolbox) * (Probability of drawing a black fuse from the second toolbox)

Probability = (3/7) * (5/7)

Scenario 2: Fuse drawn from the first toolbox is black, and the second toolbox has a white fuse:

Probability = (Probability of drawing a black fuse from the first toolbox) * (Probability of drawing a white fuse from the second toolbox)

Probability = (4/7) * (3/7)

To calculate the overall probability, we need to sum up the probabilities of both scenarios:

Probability that one fuse is white = Probability

of scenario 1 + Probability of scenario 2

Probability that one fuse is white = (3/7) * (5/7) + (4/7) * (3/7)

Probability that one fuse is white = 15/49 + 12/49

Probability that one fuse is white = 27/49

Therefore, the probability that one fuse is white is 27/49.

Explanation:

The oxide layer that forms on aluminum had a much higher melting point than the aluminum to be welded on and must removed before welding.

This is because oxide layer has a much higher melting point than the aluminum itself and can interfere with the welding process. If not removed, it can create voids or inclusions in the weld and weakens the joint and reducing its strength.

It can also contribute to porosity that can further compromise the integrity of the weld. So, we must remove the oxide layer through methods such as mechanical abrasion, chemical cleaning before proceeding with the welding process.

Explanation:

hz on a multimeter means frequency setting

On the orifice with a 50 mm in diameter opening:

(a) The volume flow rate of water through the pipe is:

\(Q = A_v v\)

where A_v = area of the orifice and v = velocity of the flow.

The area of the orifice is:

\(A_v = \pi ( \frac{d}{2} )^2 = \pi (\frac{50}{2})^2 = 1962.5 mm^2\)

The velocity of the flow is:

\(v = \sqrt{2gH} = \sqrt{2(9.81)(0.15)} = 1.715 m/s\)

Therefore, the volume flow rate is:

Q = 1962.5 mm² × 1.715 m/s = 3.375 m³/s

(b) The average velocity of the flow is:

\(v_avg = Q/A_p = Q/(\pi (\frac{d}{2})^2) = 3.375 m^3/s / (\pi (\frac{100}{2})^2) = 1.082 m/s\)

(c) The head loss caused by the orifice meter is:

\(H_L = \frac{v^2}{2g} = \frac{(1.715)^2}{2(9.81)} = 0.15 m\)

(d) The height of water column required if replaced with water manometer is:

\(H_w = \frac{\rho_m}{\rho_w} H_m = \frac{13.6}{1} (0.15) = 2.04 m\)

Therefore, the answers to your questions are:

(a) The volume flow rate of water through the pipe is 3.375 m^3/s.

(b) The average velocity of the flow is 1.082 m/s.

(c) The head loss caused by the orifice meter is 0.15 m.

(d) The height of water column required if replaced with water manometer is 2.04 m.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity.

Closing the throttle, turning off the fuel pump, setting the mixture control to idle cutoff, and simply cranking the engine is the most reliable hot start method I've found.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity. If you are unable to climb, close both throttles and land straight ahead.

The typical practice for the majority of aircraft would be to abandon takeoff if an engine failed during takeoff. In small aircraft, the pilot should turn the throttles down to idle, activate the speed brakes (if provided), and apply the brakes as needed if the engine fails before VR (Rotation Speed).

Answer:

Answer:

the first one would be correct

Explanation:

Answer:

some connecting rods have spit holes

Some connecting rods have crankshaft to help lubricate the cylinder wall or piston pin.

A crankshaft is a mechanical component that converts reciprocating motion in a piston engine into rotational motion.

The crankshaft is a rotating shaft with one or more crankpins that drive the pistons via the connecting rods.

Reduced fuel economy is one issue you'll face if your car's crankshaft isn't working properly. The reason for this is that your vehicle's fuel injectors will not efficiently direct gas to the engine.

The connecting rods' big ends are lubricated with oil that travels up an oilway drilled through the crankshaft.

From the main bearings to the big end bearings, oil is pushed. It will lubricate the cylinder walls in some engines by passing through a passage drilled in the connecting rod.

Thus, the answer is crankshaft.

Answer:

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

Explanation:

From Heat Transfer we determine that heat transfer rate due to electromagnetic radiation (\(\dot Q\)), measured in BTU per hour, is represented by this formula:

\(\dot Q = \epsilon\cdot A\cdot \sigma \cdot (T_{s}^{4}-T_{b}^{4})\) (1)

Where:

\(\epsilon\) - Emissivity, dimensionless.

\(A\) - Surface area of the student, measured in square feet.

\(\sigma\) - Stefan-Boltzmann constant, measured in BTU per hour-square feet-quartic Rankine.

\(T_{s}\) - Temperature of the student, measured in Rankine.

\(T_{b}\) - Temperature of the bus, measured in Rankine.

If we know that \(\epsilon = 0.90\), \(A = 16.188\,ft^{2}\), \(\sigma = 1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}}\), \(T_{s} = 554.07\,R\) and \(T_{b} = 527.67\,R\), then the heat transfer rate due to electromagnetic radiation is:

\(\dot Q = (0.90)\cdot (16.188\,ft^{2})\cdot \left(1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}} \right)\cdot [(554.07\,R)^{4}-(527.67\,R)^{4}]\)

\(\dot Q = 417.492\,\frac{BTU}{h}\)

Under the consideration of steady heat transfer we find that the net energy transfer from the student's body during the 20 min-ride to school is:

\(Q = \dot Q \cdot \Delta t\) (2)

Where \(\Delta t\) is the heat transfer time, measured in hours.

If we know that \(\dot Q = 417.492\,\frac{BTU}{h}\) and \(\Delta t = \frac{1}{3}\,h\), then the net energy transfer is:

\(Q = \left(417.492\,\frac{BTU}{h} \right)\cdot \left(\frac{1}{3}\,h \right)\)

\(Q = 139.164\,BTU\)

The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.

Roads that function as expressways and divided highways have high speeds and a greater risk of severe and fatal crashes.

1. Speed-related crashes: Expressways and divided highways typically have higher speed limits compared to other types of roads. The increased speed creates less time for drivers to react to hazards and increases the distance required to stop. Consequently, the risk of speed-related crashes, such as rear-end collisions or loss of vehicle control, is higher.

2. Head-on collisions: Divided highways often feature a physical barrier or median separating traffic traveling in opposite directions. However, head-on collisions can still occur due to driver error, such as wrong-way driving or crossing the median. Head-on collisions are particularly severe and have a higher likelihood of resulting in fatal or life-threatening injuries due to the combined speed of the vehicles involved.

3. Rollover accidents: Higher speeds on expressways and divided highways can increase the risk of rollover accidents, especially if drivers lose control of their vehicles. Factors such as abrupt lane changes, overcorrection, or encountering uneven road surfaces can contribute to a vehicle rolling over, leading to serious injuries or fatalities.

4. Merge and lane-change crashes: Divided highways often have multiple lanes, and drivers frequently need to merge or change lanes to enter or exit the roadway. The high speeds on these roads can make merging and lane changes challenging, increasing the risk of side-swipe or rear-end collisions if drivers fail to properly judge the speed and distance of other vehicles.

5. Reduced reaction time: The higher speeds on expressways and divided highways decrease the available time for drivers to react to unexpected events, such as sudden lane changes, stopped vehicles, or debris on the roadway. This reduced reaction time can result in more severe crashes as drivers may not have enough time to avoid a collision or mitigate its impact.

It is important for drivers on expressways and divided highways to exercise caution, adhere to speed limits, maintain a safe following distance, use turn signals when changing lanes, and remain attentive at all times.

The correct answer that successfully substitutes values into a string using a list is >>> "\n {1} years, I'll be age {0}".format([40, 10]).The correct answer is option B.

In this answer, the format() method is used to substitute values into the string. The string contains two placeholders {0} and {1}, which represent the positions where the values from the list will be inserted.

The list [40, 10] is passed as an argument to the format() method, and the values are substituted in the order they appear in the list. Therefore, the resulting string will be "\n 10 years, I'll be age 40".

Option a is incorrect because the format() method is called on a string

instead of a list. Additionally, the list is not correctly formatted.

Option c is incorrect because the variable name "V" is enclosed in quotes, making it a string instead of a variable referencing the list. Also, there is a syntax error with the closing quotation mark.

Option d is incorrect because the variable name "v" is not defined with a lowercase "v" in the code, while the string also contains an incorrect placeholder "(O)" instead of "{0}".

In conclusion, option b is the correct answer that successfully substitutes values into a string using a list.
