When does congestion collapse happen and how congestion collapse is handled at the transport layer?
Answers
TCP congestion control, which is utilized at the transport layer, is a well-known and often used close-loop control method. By adjusting the window size, which designates the number of unacknowledged packets permitted by the source process, control alters the transmission rate dynamically.
The additive increase/multiplicative decrease (AIMD) scheme is one of several techniques used by the Transmission Control Protocol (TCP) to minimize network congestion. Other schemes used by TCP include the delayed start and congestion window (CWND) schemes. The TCP congestion-avoidance algorithm serves as the cornerstone of Internet congestion management. According to the end-to-end approach, internet hosts, not the network itself, are primarily responsible for congestion control. The method is implemented in many forms and versions in the operating systems' protocol stacks of computers that connect to the Internet. TCP employs a multifaceted congestion-control method to prevent congestive breakdown. The total number of unacknowledged packets that can be in transit end-to-end is constrained by the CWND that TCP maintains for each connection. This is comparable to the sliding window flow control method employed by TCP.

a turbine is supplied with 0 6 m3 s of water from a 0.3 m diameter pipe; the discharge pipe has a 0.4 m diameter. determine the pressure drop across the turbine if it delivers 60 kw
Answers
The pressure drop across the turbine if it delivers 60 kw is 75.4KPa.
The task of providing usable output shaft power to drive the propeller falls on the turbine section of the gas turbine engine. It must also deliver energy to run the compressor and other engine accessories. This is accomplished by expanding the gas at high pressure, temperature, and velocity and transforming the resulting gaseous energy into mechanical energy in the form of shaft power.
The turbine needs a significant volume of air to generate the required amount of electricity. The compressor provides this volume of air by pulling it into the engine and compressing it to provide high-pressure air for the turbine.

What makes it challenging to build new nuclear power stations in the UK?
Answers
One of the major reasons is the high cost associated with the construction of new nuclear plants.
The construction and operation of nuclear plants require a significant amount of capital investment, which makes it difficult for investors to take the risk. Additionally, the high cost of decommissioning nuclear plants and the disposal of radioactive waste is also a major concern.
Another challenge associated with building new nuclear power stations is public opposition. Many people are skeptical about the safety of nuclear power, especially after incidents like in Japan. This has led to protests and campaigns against the construction of new nuclear plants, making it difficult for the government to get public support.
The lengthy regulatory process is also a major challenge in building new nuclear power stations in the UK. The approval process involves multiple stages and can take several years to complete. This results in significant delays and increased costs.
Furthermore, the lack of skilled labor and expertise in the nuclear industry is also a challenge. Many of the skilled workers in the industry are approaching retirement age, and there is a shortage of new workers to replace them.
In conclusion, building new nuclear power stations in the UK is a challenging task due to high costs, public opposition, regulatory hurdles, and a shortage of skilled workers. Addressing these challenges will be essential for the successful development of new nuclear power stations in the future.

A pipe 120 mm diameter carries water with a head of 3 m. the pipe descends 12 m in altitude and reduces to 80 mm diameter, the pressure head at this point is 13 m. Determine the velocity in the small pipe and the rate of discharge (in L/s)? Take the density is 1000 kg/m³.
Answers
Given:
- Diameter of the first pipe (D1): 120 mm = 0.12 m
- Diameter of the second pipe (D2): 80 mm = 0.08 m
- Head at the first pipe (H1): 3 m
- Altitude change (Δh): 12 m
- Head at the second pipe (H2): 13 m
- Density of water (ρ): 1000 kg/m³
Step 1: Calculate the velocities in the pipes using Bernoulli's equation.
Applying Bernoulli's equation between the two points in each pipe:
For the first pipe:
P1/ρ + V1²/2g + H1 = constant (1)
For the second pipe:
P2/ρ + V2²/2g + H2 = constant (2)
Since the pipes are open to the atmosphere, we can assume P1 = P2 = atmospheric pressure (approximately).
Simplifying equation (1):
V1²/2g + H1 = constant (3)
Simplifying equation (2):
V2²/2g + H2 = constant (4)
Step 2: Solve for the velocities V1 and V2.
Using equation (3) for the first pipe:
V1²/2g + 3 = constant (5)
Using equation (4) for the second pipe:
V2²/2g + 13 = constant (6)
Step 3: Solve for the velocities V1 and V2.
Since the constants in equations (5) and (6) are the same (as it is a continuous flow), we can equate the two equations:
V1²/2g + 3 = V2²/2g + 13
V1²/2g - V2²/2g = 10
(V1² - V2²)/(2g) = 10
V1² - V2² = 20g
V1² = V2² + 20g (equation 7)
Step 4: Convert the diameter to radius for each pipe.
r1 = D1/2 = 0.12/2 = 0.06 m
r2 = D2/2 = 0.08/2 = 0.04 m
Step 5: Calculate the rate of discharge (Q) using the continuity equation.
The continuity equation states that the product of the cross-sectional area (A) and the velocity (V) is constant in a flowing fluid.
Q1 = Q2 (since it is a continuous flow)
A1V1 = A2V2
πr1²V1 = πr2²V2
(r1²V1)/(r2²) = V2
Step 6: Calculate the velocity in the smaller pipe (V2).
Substitute the values in equation (7):
V1² = V2² + 20g
(V1²r2²)/(r1²) = V2²
(0.06²V2²)/(0.04²) = V2²
V2² = (0.06²V1²)/(0.04²) [Substitute V1² = 2g(3) from equation (5)]
V2² = (0.06² × 2g × 3)/(0.04²)
V2² = 0.27g
V2 = √(0.27g)
Step 7: Calculate the rate of discharge (Q) in L/s.

Pressure altitude is the vertical distance above the standard datum plane, whereas Density altitude is the height in the International Standard Atmosphere at which the air density is equal to the actual air density at the place of observation.
Pressure Altitude Pressure Altitude is a term used to describe the altitude of an aircraft above a given datum plane. It is measured by an altimeter that has been calibrated to read pressure rather than altitude. This is because pressure is directly proportional to the altitude, and so changes in pressure can be used to determine changes in altitude. Density Altitude Density Altitude is the altitude in the International Standard Atmosphere (ISA) at which the air density is equal to the actual air density at the place of observation.
It is affected by the air temperature, atmospheric pressure, and humidity, and is usually higher than the pressure altitude.Q2: The effect of pressure, humidity, and temperature on air density is described below:Air Pressure: When air pressure increases, air density also increases.Humidity: Humidity decreases air density because water molecules are lighter than air molecules and displace some of the air molecules in a given space.Temperature: When air temperature increases, air density decreases.

Answers
Since the armature is wave wound, the magnetic flux per pole is 0.0274 Weber.
Given the following data:
Emf = 520 VoltsSpeed = 660 r.p.mNumber of armature conductors = 144 slotsNumber of poles = 4 polesNumber of parallel paths = 2To find the magnetic flux per pole:
Mathematically, the emf generated by a DC generator is given by the formula;
\(E = \frac{\theta ZN}{60}\) × \(\frac{P}{A}\)
Where:
E is the electromotive force in the DC generator.Z is the total number of armature conductors.N is the speed or armature rotation in r.p.m.P is the number of poles.A is the number of parallel paths in armature.Ф is the magnetic flux.First of all, we would determine the total number of armature conductors:
\(Z = 144\) × \(2\) × \(3\)
Z = 864
Substituting the given parameters into the formula, we have;
\(520 = \frac{\theta (864)(660)}{60}\) × \(\frac{4}{2}\)
\(520 = \theta (864)(11)\) × \(2\)
\(520 = 19008 \theta \\\\\Theta = \frac{520}{19008}\)

a tensile specimen with a 12mm initial diameter and 50mm gage length reaches maximum load at 90KN and fractures at 70KN
the minimum diameter at fracture is 10mm
determine the engineering stress at maximum load and the true fracture stress.
Answers
Answer:
i) 796.18 N/mm^2
ii) 1111.11 N/mm^2
Explanation:
Initial diameter ( D ) = 12 mm
Gage Length = 50 mm
maximum load ( P ) = 90 KN
Fractures at = 70 KN
minimum diameter at fracture = 10mm
Calculate the engineering stress at Maximum load and the True fracture stress
i) Engineering stress at maximum load = P/ A
= P / \(\pi \frac{D^2}{4}\) = 90 * 10^3 / ( 3.14 * 12^2 ) / 4
= 90,000 / 113.04 = 796.18 N/mm^2
ii) True Fracture stress = P/A
= 90 * 10^3 / ( 3.24 * 10^2) / 4
= 90000 / 81 = 1111.11 N/mm^2
