Answer: 1. Capturing fibers shed from tyres
The Tyre Collective start-up describes tyres as “the stealthy pollutant you never thought about.”
“It’s common knowledge that tyres wear down, but nobody seems to think about where it goes, and we were really shocked to discover that tyre particles are the second-largest microplastic pollution [after single-use plastics] in our oceans,” Hugo Richardson, one of co-founders of the company, said.
The particles from tyres also infuse into the air we breathe, making up to 50% of air particle emissions from road transport.

The length of the horizontal direction must be large enough to capture the two large recirculations on each side of jet and to limit the influence of the buffer domain inside of the domain of interest. Preliminary bidimensional simulations have been used to test the influence of the length of the horizontal direction. We concluded that a value of Hx/e = 40 is sufficient. In the framework of air curtain applications, the opening ratio is fixed to 10 for all cases. The choice of the length of the homogeneous direction (Oz) is less obvious. Indeed, the periodic boundary conditions along the homogeneous direction are justified only if the transverse dimension Hz is large enough to capture the largest structures of the flow. Consequently, the fluctuations must be practically decorrelated on a half-period (Hz/2). In the absence of two point correlations available in the literature for plane jets with short impingement distance, we considered successively two different transverse dimensions: Hz/e = π in accordance with the simulations of Hoffmann and Benocci (1994); Voke et al. (1995), then a double dimension Hz/e = 2π. Note that Cziesla et al. (2001) set the length of the homogeneous direction to 2. Beaubert and Viazzo (2001) note an overlapping problem on the transverse two-point correlations of the different velocity components in the plane of symmetry of the jet for the smallest width. Therefore, a width of 2π for the transverse direction is rather advised for the ratio Hy/e = 10 and in this range of Reynolds numbers. Table 1 contains the characteristics of the three simulations.

The correct matching would be:
Mass production system -> focuses on manufacturing large and continuous product runs.
The other matching pairsLean manufacturing system -> focuses on the reduction of waste in the manufacturing process.
Agile manufacturing system -> focuses on the ability to adapt to customer and market changes.
Assembly line production system -> focuses on improving worker efficiency by making tasks short and repetitive.
The mass production system emphasizes the production of a high volume of products in a consistent manner. The lean manufacturing system has the objective of minimizing or eliminating waste.
The agile manufacturing system places great importance on accommodating alterations from customers and the market. The assembly line manufacturing technique enhances worker productivity by assigning brief and repetitive tasks.

10.) A solid circular titanium control rod at 7,000 lb axial tension force where stress must not
exceed 42,000 psi. Assume that the modulus of elasticity of the titanium is 16,500,000 psi
and that the rod must elongate no more than 0.20 in. Determine (a) the minimum rod
diameter (precision 0.00) and (b) the maximum rod length (precision of 1).
Answers
The minimum rod diameter is 0.46 in and the maximum rod length is 78.6 in.
What is diameter?Diameter is defined as the distance that runs through the center of a circle from one point to another on its surface. It can also be thought of as the circle's longest chord. The diameter of a sphere can be defined using either of the two methods.
Given tension axial force = 7000 lb
Maximum axial tensile strength = 42000 psi
σ = P /A = P / λ / 4 x d²
The minimum rod diameter = 0.46
Elongation in rod = 0.2 in
= FL / AE
Maximum length of rod = 78.6 in
Thus, the minimum rod diameter is 0.46 in and the maximum rod length is 78.6 in.

It is given that 50 kg/sec of air at 288.2k is iesntropically compressed from 1 to 12 atm. Assuming a calorically perfect gas, determines the exit temperature and the compressor's input power.
Answers
The exit temperature is 586.18K and compressor input power is 14973.53kW
Data;
Mass = 50kg/sT = 288.2KP1 = 1atmP2 = 12 atmExit TemperatureThe exit temperature of the gas can be calculated isentropically as
[tex]\frac{T_2}{T_1} = (\frac{P_2}{P_1})^\frac{y-1}{y}\\ y = 1.4\\ C_p= 1.005 Kj/kg.K\\[/tex]
Let's substitute the values into the formula
[tex]\frac{T_2}{T_1} = (\frac{P_2}{P_1})^\frac{y-1}{y} \\\frac{T_2}{288.2} = (\frac{12}{1})^\frac{1.4-1}{1.4} \\ T_2 = 586.18K[/tex]
The exit temperature is 586.18K
The Compressor input powerThe compressor input power is calculated as

Given: A=1, B=1, C=1 for a 3-input NOR gate, what is the output value?
Answers
Answer:
0
Explanation:
A NOR gate gives you the inverted output of an OR function. In numerical terms, the OR function gives you the maximum of the inputs:
A+B+C = max(A, B, C) = max(1, 1, 1) = 1
Then the output of the NOR function is its inverse:
(A+B+C)' = (1 -max(A, B, C)) = 1 -1 = 0
The output value is 0.
