In order for a tolerance zone shape to be cylindrical, what symbol must be present in the second compartment of the Feature Control Frame?

Answer:

To calculate the steady state flux of atomic hydrogen through a steel vessel, we need to use Fick's first law, which states that the flux (J) is equal to the diffusivity (D) multiplied by the concentration gradient (dC/dx).

First, we need to calculate the concentration gradient by dividing the difference in hydrogen concentration between the inside and outside surfaces by the wall thickness of the vessel. The inside surface is kept saturated with hydrogen at a concentration of 4.5 moles/m3, and the outside surface is exposed to the atmosphere, which has a hydrogen concentration of 0 moles/m3. Therefore, the concentration gradient is (4.5 - 0) moles/m3 / (4 mm) = 1.125 moles/m3 mm.

Next, we need to substitute this value into Fick's first law along with the diffusivity of hydrogen in steel, which is given as 0.1 mm2/s. This gives us the steady state flux as J = (-0.1 mm2/s) * (1.125 moles/m3 mm) = -0.01125 moles/s mm2.

Finally, we need to convert the units of the flux from moles/s mm2 to moles/s m2. To do this, we can multiply the flux by 1,000 to convert the units of millimeters to meters, giving us a final steady state flux of -0.01125 moles/s mm2 * 1,000 = -1.125 moles/s m2.

IF THE VESSEL CONTAINS 20 MOLES OF HYDROGEN, CALCULATE THE TIME TAKEN TO DISSIPATE ALL OF THE HYDROGEN OF THAT THE VESSEL HAS A SURFACE AREA OF 3 M2.

To solve this problem, we need to first calculate the flux of atomic hydrogen through the vessel using Fick's first law:

J = -D(dC/dx)

where J is the flux, D is the diffusivity of hydrogen in steel, and dC/dx is the concentration gradient.

Given that the diffusivity of hydrogen in steel is 0.1 mm2/s, the inside concentration is 4.5 moles/m3, and the outside concentration is 0, the concentration gradient is 4.5 moles/m3.

Plugging these values into the equation above, we get:

J = -0.1 mm2/s * 4.5 moles/m3 = -0.45 moles/s-m2

Next, we need to calculate the time it takes to dissipate all 20 moles of hydrogen from the vessel. We can do this by dividing the total number of moles of hydrogen by the flux:

t = 20 moles / (-0.45 moles/s-m2) = 44.44 s

So it would take approximately 44.44 seconds to dissipate all of the hydrogen from the vessel.

Explanation:

SELF EXPLANATORY

The time taken is 44.44 seconds to dissipate all of the hydrogens from the vessel.

To solve this problem, we need to first calculate the flux of atomic hydrogen through the vessel using Fick's first law:

J = -D(dC/dx)

where J is the flux, D is the diffusivity of hydrogen in steel, and dC/dx is the concentration gradient.

Given that the diffusivity of hydrogen in steel is 0.1 mm²/s, the inside concentration is 4.5 moles/m³ and the outside concentration is 0, the concentration gradient is 4.5 moles/m³.

Plugging these values into the equation above, we get:

J = -0.1 mm²/s * 4.5 moles/m³ = -0.45 moles/s-m²

Next, we need to calculate the time it takes to dissipate all 20 moles of hydrogen from the vessel. We can do this by dividing the total number of moles of hydrogen by the flux:

t = 20 moles / (-0.45 moles/s-m2) = 44.44 s

So it would take approximately 44.44 seconds to dissipate all of the hydrogen from the vessel.

Explanation:

1. Longitudinal tensile stress can be obtained by obtaining the strength and volume of the fiber reinforcement. The derived formula is given by;

σcl = σm (1 - Vf) + σfVf

Substituting the figures, we will have;

45(1 - 0.30) + 3600(0.30)

45(0.70) + 1080

31.5 + 1080

= 1111.5MPa

2. Longitudinal modulus of elasticity or Young's modulus is the ability of an object to resist deformation. The derived formula is given by;

Ecl = EmVm + EfVf

Substituting the formula gives;

= 2.4 (1 - 0.30) + 131 (0.30)

= 2.4(0.70) + 39.3

= 16.8 + 39.3

= 56.1GPa

Using the appropriate relation, the longitudinal tensile stress and the longitudinal modulus are 1111.50 and 56.10 respectively.

Longitudinal tensile stress can be obtained using the relation :

Substituting the values into the relation:

45(1 - 0.30) + 3600(0.30)

45 × 0.70 + 1080

31.5 + 1080

= 1111.50 MPa

2.)

Longitudinal modulus of elasticity is obtained using the relation :

Substituting the values thus :

2.4 (1 - 0.30) + 131 (0.30)

= 2.4 × 0.70 + 39.3

= 16.8 + 39.3

= 56.10 GPa

Hence, the longitudinal tensile stress and the longitudinal modulus are 1111.50 and 56.10 respectively.

Answer:

True

Explanation:

It's just because of the processing

The amount of torque produced by a motor at the instant the load causes it to stall is called the "stall torque." When a motor operates at its rated voltage and frequency, it is designed to deliver a specific amount of torque to drive the load it is connected to.

Torque is the rotational force exerted by the motor to generate motion or maintain the position of the load. The motor's ability to produce torque depends on factors such as its design, construction, and power supply.

Under normal operating conditions, the motor generates torque that is sufficient to overcome the load and maintain rotation. However, when the load exceeds the motor's torque capability, the motor reaches its maximum torque output, known as the stall torque. At this point, the motor cannot produce enough torque to continue rotating, and it comes to a halt or stalls.

The stall torque is a crucial parameter in motor specifications as it provides information about the motor's ability to handle heavy loads or start-up conditions where a high torque is required. It represents the maximum torque output that the motor can generate when it is unable to overcome the load and maintain rotation.

Motor manufacturers provide stall torque ratings in motor datasheets or technical specifications. It is important to consider the stall torque when selecting a motor for applications where the load demands high starting torque or requires the motor to handle heavy loads without stalling.

Answer:

a)\(Q_H=16.4kW\)

b) \(w=5.467\)

c)  \(w=1.2345\)

Explanation:

From the question we are told that:

Interior temperature \(TH = 20 °C\)

outside temperature is \(TC = 2 °C\)

Rate \(H=16.4kW\)

a)

Generally electric resistance heating is the heat transfer from interior building

Therefore

\(Q_H=R\)

\(Q_H=16.4kW\)

b)

COP =3

Generally the equation for coefficient of performance is mathematically given by

\(COP=\frac{Q_H}{w}\)

Therefore

\(w=\frac{Q_H}{COP}\)

\(w=16.4/3\)

\(w=5.467\)

c)

Generally the equation for coefficient of performance is mathematically given by

\(COP_r=\frac{TH}{TH-TC}\)

\(COP_r=\frac{20+273}{(20+273)-(2+273)}\)

\(COP_r=16.2\)

Therefore

\(w=1.2345\)

\(w=20/16.2\)

Trim heel and transducer separations are two potential errors that can affect the accuracy of a ship's draft and trim readings.

Trim heel refers to the angle of inclination of a ship in the water, which can affect the readings taken by the ship's sensors. If the ship is not perfectly level in the water, the sensors may not provide accurate measurements of the draft or the amount of cargo on board. This can result in incorrect calculations of the ship's stability, which can lead to dangerous situations.

Transducer separation is another potential source of error that can affect the accuracy of a ship's draft readings. Transducers are sensors that are mounted on the hull of a ship to measure the water level and provide information on the ship's draft. If these sensors are not properly calibrated or if they are separated from the hull, they may provide inaccurate readings, which can lead to errors in the ship's stability calculations.

In summary, trim heel and transducer separations can result in inaccurate readings of a ship's draft and cargo load, which can affect the ship's stability and safety. It is important for ship operators to regularly calibrate and maintain their sensors to minimize the risk of errors due to trim heel and transducer separations.

Hope this helps!

Here is a possible solution for a bounded-buffer monitor with embedded buffers:

csharp

Copy code

monitor BoundedBuffer

   buffer : array[1..N] of item

   in, out, count : integer

   procedure insert(item)

       if count = N then wait()     // buffer is full, wait

       buffer[in] := item           // insert item into buffer

       in := (in mod N) + 1         // increment index, wrap around if necessary

       count := count + 1           // update count

       if count = 1 then signal()   // buffer was empty, signal

   procedure remove() returns item

       if count = 0 then wait()     // buffer is empty, wait

       item := buffer[out]          // remove item from buffer

       out := (out mod N) + 1       // increment index, wrap around if necessary

       count := count - 1           // update count

       if count = N-1 then signal() // buffer was full, signal

       return item

end monitor

In this algorithm, the monitor has an embedded buffer, represented as an array of N items, where N is the maximum number of items the buffer can hold. The in, out, and count variables keep track of the buffer's state. The insert and remove procedures are used to add and remove items from the buffer, respectively.

The insert procedure checks if the buffer is full (count = N) and if so, waits by calling the wait procedure (assumed to be part of the monitor's implementation). If the buffer is not full, the item is inserted into the buffer at the in index, which is then incremented and wrapped around if necessary to ensure it remains within the bounds of the array. The count variable is incremented to reflect the new number of items in the buffer. If the buffer was previously empty (count = 1), the signal procedure is called to wake up any threads waiting to remove items from the buffer.

Example 1: High-rise office building The first project is a 20-story high-rise office building that is still in the planning phase. This building has been designed to meet the minimum fire safety requirements of the building codes. The design is based on traditional methods where the objective is to protect the occupants from fire until the fire department arrives.

Example 2: Healthcare facility The second project is a new hospital that is under construction. This hospital will have several departments, including an emergency room, surgery rooms, and patient wards. Due to the complexity of the hospital, the building codes have been difficult to implement in the design of the hospital. Performance-based engineering could be used to demonstrate how the hospital can meet the safety objectives of the building owner and local fire authorities.
