The purpose behind the use of control charts is to distinguish between common cause variation and special cause variation in a process.

Common cause variation is a natural part of any process and is caused by random fluctuations in the system. Special cause variation, on the other hand, is caused by a specific event or factor that can be identified and addressed. Control charts help to monitor a process over time, by plotting data points on a graph, and determining if they fall within the expected range of variation.

If the data falls within the expected range, then the process is considered to be under control. If the data falls outside of the expected range, then there may be a special cause present that requires investigation and corrective action, control charts help to identify and distinguish between common cause and special cause variation, allowing for continuous improvement and quality control in a process.

Answer:

A)  222.58 kJ / kg

B)  0.8897 M^3/ kg

c)  0.7737 m^3/kg

D)  746.542 k

E)  536.017 kj/kg

efficiency = 58% ( approximately )

Explanation:

Given Data :

Gas constant (R) =  0.287 kJ/ kg.K

T1 = 310 k

P1 ( Kpa ) = 100

r = 11.5 ( compression ratio )

rp = 1.95 ( pressure ratio )

A ) specific internal energy at state 1

 = Cv*T1 =  0.718 * 310 = 222.58 kJ / kg

B) Relative specific volume at state 1

= P1*V1 = R*T1 ( ideal gas equation )

V1 = R*T1 / P1 = (0.287* 10^3*310 ) / 100 * 10^3

V1 = 88.97 / 100 = 0.8897 M^3/ kg

C ) relative specific volume at state 2

Applying  r ( compression ratio) = V1 / V2

11.5 = 0.8897 / V2

V2 = 0.8897 / 11.5 = 0.7737 m^3/kg

D) The temperature (k) at state 2

since the process is an Isentropic process we will apply the p-v-t relation

\(\frac{T1}{T2} = (\frac{V1}{V2}^{n-1} ) = (\frac{P2}{P1} )^{\frac{n-1}{n} }\)

hence T2 = \(9^{1.4-1} * 310\) = 2.4082 * 310 = 746.542 k

e) specific internal energy at state 2

= Cv*T2 = 0.718  * 746.542 = 536.017 kj/kg

efficiency = output /input = 390.3511 / 667.5448 ≈ 58%

Designing a sequential logic circuit to detect the sequence 0101 using a Mealy FSM model involves creating a state table, determining the next state and output based on present input and state, and using JK flip flops and excitation tables. The circuit returns to the initial state when any other sequence is detected.

Designing the sequential logic circuit to detect the sequence 0101 using Mealy FSM model requires following steps and considerations. Mealy FSM model is different from Moore FSM model in the way that Mealy model produces output only when the state of circuit changes.

The output of the circuit is dependent on the present state as well as the present input. Sequence detection using Mealy FSM model The first step is to create a state table representing the input sequence. For this, we need to specify the input bits, present state and the output.

Here's the state table for detecting 0101 sequence using JK flip flops:   Present State Input Next State OutputQ1 Q0 x Q1+ Q0+ z 0 0 0 0 1 0 0 1 0 1 1 0 1 1 1 0 0 0 1 0 1 1 1 0 0

The output of the sequential circuit in this example is 1 whenever it detects the pattern 0101. When the state is S3, it is always followed by the state S0, so when the circuit is in state S3, and input of 0 is detected, the output will go high indicating the sequence has been detected. This is repeated for the next 3 states when the sequence is detected.

The circuit returns to state S0 and starts the detection over when any other sequence is detected. As we are using JK flip flops, we must also make use of excitation tables to determine the JK flip flop input when transitioning from one state to the next.

We must also encode the states to binary to simplify the circuit. The state table with binary encoding for this example is shown below:  

Present State Input Next State OutputQ1 Q0 x Q1+ Q0+ z 0 0 0 0 1 0 0 0 1 1 0 1 1 1 0 0 0 1 0 1 1 1 0 0

Whenever the circuit is in the state S3, an input of 0 will set the output high, indicating the pattern 0101 has been detected. If the input does not match the pattern, the circuit returns to state S0.

Answer:

The light from the first LED will appear as yellow while the light from the second LED won't appear as Yellow light when passed through a diffraction grating

Explanation:

There are two types of LED's

First LED emits only yellow light  with wavelength of 590 nm

Second LED : emits red light with wavelength of 630 nm and emits green light with a 540 nm wavelength

The second LED produces a yellow light because of the mixture of red and green lights

therefore when the light from the SECOND LED is passed through a  diffraction grating, the light is split into its components ( i,e green and red lights ) this is because the lights are not on the same wavelength

angular velocity of the reel after 3 seconds is 5.11 rad/s. We cannot calculate the frictional force without knowing the coefficient of kinetic friction.

To solve this problem, we need to use the principle of conservation of energy and the equation of rotational motion.
First, let's calculate the moment of inertia of the reel. The moment of inertia is given by the formula:
I = Mk^2
where M is the mass of the reel and k is the radius of gyration about its center of gravity. We are given that the weight of the reel is 150 Ib, so we can convert this to mass using the formula:
M = W/g
where W is the weight of the reel and g is the acceleration due to gravity. Substituting the given values, we get:
M = 150/32.2 = 4.66 slugs
Now we can calculate the moment of inertia:
I = Mk^2 = 4.66 (1.25)^2 = 7.3125 slug-ft^2
Next, let's find the work done by the torque on the reel. The work done is given by the formula:
W = MΔθ
where M is the torque and Δθ is the angular displacement. We are given that the torque is 25 Ib ft and the reel starts from rest, so initially Δθ = 0. At the end of 3 seconds, the angular displacement is given by:
Δθ = ωt + (1/2)αt^2
where ω is the final angular velocity, α is the angular acceleration, and t is the time. We are asked to find the final angular velocity after 3 seconds, so we rearrange the equation and substitute the given values:
ω = (Δθ - (1/2)αt^2)/t = (0.5)(α)(t) = (0.5)(τ/I)(t)
where τ is the torque and I is the moment of inertia. Substituting the given values, we get:
ω = (0.5)(25/7.3125)(3) = 5.11 rad/s
Finally, let's find the frictional force acting on the reel. The frictional force is given by the formula:
f = μN
where μ is the coefficient of kinetic friction and N is the normal force. The normal force is equal to the weight of the reel, which we already calculated to be 150 Ib. We are not given the value of μ, so we cannot calculate the frictional force.

To calculate the center temperature of the brick column at t = 1 hour after the start of the cooling, we need to use the heat equation, which is a partial differential equation describing how heat flows through a material over time. The heat equation for a two-dimensional steady state problem is given by:

∇²T = α ∂T/∂t

Where T is the temperature, α is the thermal diffusivity, and t is time.

The solution to this equation can be found using the semi-infinite solid solution which is given by

To = Ti + (T∞-Ti) erfc(x/2*√(αt))

where,

To is the center temperature,

Ti is the initial temperature of the column,

T∞ is the ambient temperature,

x is the distance from the surface of the column, α is the thermal diffusivity, and

t is time.

In this case,

To = 225 + (25-225) erfc(5/2√(0.510^-6 * 3600))

Plugging in the given values, the center temperature is around Tₒ = 225 + (25-225) erfc(0.0156) ≈ 185.6 °C

When constructing a railroad, two connecting rails need to be given a small separation, to allow for expansion during the summer months.

If the beams are made of steel in a factory at 23oC at a length of 3 m, and they can be expected to heat up to temperatures of 50oC, what should the spacing between steel beams beThe length of the rail is 3 m or 300 cm. Let's assume that the rail expands equally from both sides. So the expansion of each rail would be half of the total expansion, i.e. (50-23) / (2 x 100) = 0.135 cm/cm.∆L = L0 α ∆TSubstituting values:∆L = 300 x 0.135 x 27 = 1094.5 micronsNow, this is the total expansion in both the rails together, so the expansion in one rail would be 1094.5 / 2 = 547.25 microns.

∆L = αL0 ∆T and α = coefficient of linear expansionThe distance between the rails is the difference in length after expansion. This would be 547.25 / 100 = 5.4725 cm. So, the distance between rails should be increased by 5.4725 cm. Hence the spacing between steel beams should be 5.4725 cm more than the original distance.
