If we tried to further accelerate a Supersonic fluid with a diverging diffuser, the pressure will decrease due to an increase in area. This can be described as :
dA/A = dP/ρV² (1-M²) for supersonic flow Mach Number, M: M > 11 - M² < 0 (dA/A) = -K (dP/ρV²)k = 1-M²
What is Supersonic Fluid?Supersonic flow fields have Mach numbers greater than one at every location. Supersonic flows are usually characterized by the presence of shock waves, which cause abrupt changes in flow characteristics and streamlines (in contrast to the smooth, continuous variations in subsonic flows).
Supersonic and subsonic relate to speeds that are faster or slower than the speed of sound, respectively. Supersonic means traveling faster than the speed of sound, which is 343.2 m/s (1,126 ft/s). Subsonic speeds are defined as anything moving slower than the speed of sound.

7. what will be stronger: a blend of stainless steel and copper powder that is compacted and sintered, or a stainless steel powder that is compacted, sintered, and infiltrated by copper?
When considering all blended, compacted, sintered and infiltrated components, the components that are made from infiltrated parts have no porosity. These infiltrated parts are the strongest ones among the remaining processes. Hence, the stainless steel components which are powdered, compacted, sintered, and infiltrated by copper are the strongest.
What is Stainless steel?
Steels that include at least 10.5% chromium, less than 1.2% carbon, and other alloying elements are known as stainless steels. Other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc., can be added to stainless steel to further improve its mechanical and corrosion resistance.
Sintered steel alloys are increasingly being used in mechanical parts. However, the better mechanical and corrosion-resistant qualities needed for sintered materials can be obtained by lowering porosity. The copper infiltration technique is effective here.
A measured quantity of copper-base alloy is spread over the surface of a porous ferrous compact during the copper infiltration process. The two components are then sintered at a temperature (>2000°F), causing the copper alloy to melt and flow through capillary action into the porosity of the ferrous compact. After the cooling process is finished, the copper alloy permanently solidifies inside the ferrous framework.
The infiltration procedure increases density, seals the sintered components, and makes the part corrosion resistant. The mechanical properties (hardness, toughness, strength, etc.) are also enhanced by this process.

a fatigue test was conducted in which the mean stress was 60 mpa (8702 psi), and the stress amplitude was 230 mpa (33360 psi). (a) compute the maximum stress level. mpa (b) compute the minimum stress level. mpa (c) compute the stress ratio. (d) compute the magnitude of the stress range. mpa
The ratio of the least to highest stress is known as the stress ratio. 345 mpa is the greatest stress level.
Explain about the maximum stress level?
The mean stress is 60 mpa. The highest tensile stress and the minimum compressive stress, respectively, are denoted by the words "maximum stress" and "minimum stress." The stress range was established using the absolute difference between the highest and lowest stress.
Maximum stress level = 1/2 of the maximum and minimum stresses.
Then,
60 = 1/2 (Maximum stress minus Minimum stress)
230 = Maximum Stress plus Minimum Stress - (1)
As opposed to that,
Amplitude is= half of the maximum and minimum stresses.
120 = 1/2(Max. stress - Min. Stress) (Max. stress - Min. Stress)
460 equals Maximum Stress - Minimum Stress - (2)
Solving equations (1) and (2) yields:
Equation (1) + (2) 230 = Maximum stress + Minimum stress

The results of the calculations are (a) P = 37.97 kN and (b) P = 35.62 kN.
The surface won't be cut if you press the flat section of the knife against the fruit. The force is dispersed over a wide area.
Using the parameters and figure provided in the problem, we have:
A = b*h = 0.14*0.24 = 0.0336 m^2
S = (b*h^2)/6 = (0.14*0.24*0.24)/6 = 0.001344 m^3
q = 5400*0.0336 = 181.44 N/m
(a) The load P at 8.5 MPa = 8.5*106 Pa (allowable bending stress)
σ = M/S
M = *S thus equals 0.001344*8.5*106 = 11424 Nm.
Aside from that
M = (P*L/4) + (q*L^2)/8
11424 = (P*1.2/4) + (181.44*1.2^2)/8
11424 = 0.3*P + 32.6592
P = (11424-32.6592)/0.3 = 37.97 kN
(b) If (allowable shear stress) = 0.8 MPa, then the value of P is equal to 0.8*106 Pa.
(2*A*τ/3) = P/2 + q*L/2
(2*0.0336*0.8*10^6)/3 = P/2 + 181.44*1.2/2
17920 = P/2 + 108.864
P = (17920 - 108.864) * 2 = 35.62 kN.

a cylindrical rod 380 mm long and having a diameter of 10.0 mm is to be subjected to a tensile load. if the rod is to experience neither plastic deformation nor an elongation of more than 0.9 mm when the applied load is 24,500 n, which of the four metals or alloys listed below are possible candidates? justify your choice(s). (2 points)
Answer:
Steel
Explanation:
Aluminium and copper alloys are not viable options because their permissible strain is less than the rod's estimated strain.
What is Strain?When an object is stressed, the amount of deformation or lengthening is measured as strain. Strain is typically stated as a ratio or percentage of the original length, area, or volume of the object. In other terms, strain is the amount of deformation in relation to an object's initial size or shape.
Calculating the stress and strain that the cylindrical rod would encounter under the specified conditions and comparing it to the permitted stress and strain values for each material will help us choose which of the four metals or alloys listed below are likely choices.
Let's begin by determining the rod's cross-sectional area:
Area = πr^2 = π(5 mm)^2 = 78.54 mm^2
The stress can then be calculated by:
[tex]Stress = Force / Area = 24,500 N / 78.54 mm^2 = 312.5 MPa[/tex]
We must apply the following formula to determine the strain:
Elongation / Initial Length = Strain
Given that the elongation shouldn't be greater than 0.9 mm:
Strain = 0.9mm/380mm =0.00237
Now that we have the stress and strain values and the permissible values for each material, we can compare them:
Allowable strain in aluminium alloy is 0.003 and allowable stress is 275 MPa.Steel alloy: 450 MPa of stress and 0.002 of strain are permitted.Copper alloy: 205 MPa of stress and 0.0035 of strain are permitted.Allowable stress for titanium alloy is 880 MPa, while allowable strain is 0.002.Therefore, due to their permissible stress and strain being more than or equal to that calculated for the cylindrical rod under the specified conditions, both the steel alloy and titanium alloy are potential options based on the comparison made above.

n order to adjust the mix to increase the compressive strength, the water-to-cement ratio is reduced to 0.45. will the quantity of coarse aggregate increase, decrease, or stay the same?
The strength reduces as the w/c ratio rises. The typical w/c ratio needed to completely hydrate cement is 0.42.
Beyond this point, additional water makes concrete easier to work with for compaction but is not required for hydration. A larger water-to-cement ratio results in wider gaps between the cement aggregates, which affects the compaction. Consequently, rising moisture levels result in decreased concrete durability and compressive strength.

What is PN junction?A P-N junction is the boundary or interface between the p-type and n-type semiconductor material types inside of a semiconductor.The process of doping produces the P-N junction in a semiconductor.In an electrical circuit, a diode (PN junction) makes it easier for current to flow in one way than the other.While reverse biasing is applying a voltage across a diode in the opposite direction, forward biasing refers to applying a voltage across a diode that facilitates easy current passage. High resistance is present in the p-n junction diode's depletion zone.As a result, the depletion region functions as an insulating or dielectric substance.P-n junction diodes can therefore be compared to parallel plate capacitors.Transition capacitance is the measurement of how much capacitance changes as voltage increases.

a transformer has 880 turns and 62 turns for the primary and secondary respectively. with no load on the secondary and a primary voltage of 2058.06 v, what is the output voltage of the secondary?
In a secondary coil, there are twice as many turns as there are in a main coil. A transformer with a turns ratio of 2:1 will have 100 primary turns and 50 secondary turns.
As a result, 60 volts will be impressed on the secondary if the primary is at 120 volts. Therefore, by multiplying both sides by N p, we may find N s, which equals N pV s over V p. The voltage drop is produced by a step-down transformer, which has a secondary coil with only 30 turns and 400 turns multiplied by 9.00 volts divided by 120 volts.
