Kinetic energy turbines, also called free-flow turbines, generate electricity from the kinetic energy present in flowing water rather than the potential energy from the head. The systems can operate in rivers, man-made channels, tidal waters, or ocean currents. Because kinetic systems utilize a water stream's natural pathway, they do not require diversion of water through man-made channels, riverbeds, or pipes, although they might have applications in such conduits. Kinetic systems do not require large civil works because they can use existing structures, such as bridges, tailraces, and channels. so it doesnt

The average temperature throughout the winding is approximately 137.5°C.

To solve this problem, we need to use the formula for the resistance-temperature relationship of copper:

R2 = R1 [1 + α(T2 - T1)]

where R1 is the resistance of the winding at the initial temperature T1, R2 is the resistance of the winding at the final temperature T2, and α is the temperature coefficient of resistance of copper.

We can rearrange the formula to solve for the final temperature T2:

T2 = (R2/R1 - 1) / α + T1

First, we need to calculate the resistance of the winding at the initial temperature T1 = 17°C:

R1 = V1 / I1 = 440 V / 2.3 A = 191 Ω

Next, we need to calculate the resistance of the winding at the final temperature, which we can do using Ohm's law:

R2 = V1 / I2 = 440 V / 1.9 A = 231.6 Ω

Now we can plug in these values into the formula for T2:

T2 = (231.6/191 - 1) / 0.00426 + 17 = 137.5°C

Explanation:

True stress ( psi )       True strain

49300                          0.11

61300                           0.21

Determine the true stress necessary to produce a true plastic strain of 0.25

бT1 = 49300

бT2 = 61300

бT3 = ?

∈T1 = 0.11

∈T2 = 0.21

∈T3  = 0.25

note : бTi = k ∈Ti^h

∴ 49300 = k ( 0.11 )^h ----- ( 1 )

   61300 = k ( 0.21)^h ------ ( 2 )

solving equations 1 and 2 simultaneously

49300/61300 = ( 0.11 / 0.21 )^h

0.804 = (0.52 )^h

next step : apply logarithm

log  ( 0.804 ) = log(0.52)^h

h = log 0.804 /  log (0.52)

  =  0.33

back to equation 1

49300 = k ( 0.11 )^0.33

k = 49300 / (0.11)^0.33

 = 102138

therefore бT3 = K (0.25)^h

                        = 102138 ( 0.25 )^ 0.33

For the similarity of Froude number:

⇒  \(\frac{V_{m}}{\sqrt{g_{m}l_{m}} }=\frac{V}{\sqrt{gl} }\)

Here,

\(l = length\)

\(g_{m}=g\)

⇒  \(\frac{V_{m}}{V}=\sqrt{\frac{l_{m}}{l} }\)

    \(V_{m}=\sqrt{\frac{1}{50} }\times number \ of \ knots\)

         \(=\sqrt{\frac{1}{50}}\times 15\)

         \(=2.12 \ knots\)

Now,

⇒  \(1 \ knots=0.514\times 3.281\)

The most desired level of coupling is a) no coupling.

This means that there is no interaction between different parts of a program, and each part can operate independently. No coupling is also known as zero coupling. When two modules are not related to each other in any way, it is referred to as no coupling. No coupling is often used as a model when creating large systems. This is due to the fact that it allows for a greater degree of flexibility in design and development. Furthermore, if a particular module of a program fails, it will not affect the other modules because they are not linked in any way.

When data-coupling is used, it becomes difficult to make any modifications in the data format. The module that is using the data should also be aware of the structure of the data. When the structure of data is changed, the coupling is also changed, and it may cause a malfunction. Therefore, it is recommended to keep the data as simple as possible, to avoid any complexities.

Answer:

Maneuvering speed.

Explanation:

The speed above which an airplane will experience structural damage when a load is applied, instead of stalling, is called the maneuvering speed and varies with weight.

In aeronautical engineering, the maneuvering speed (Va) of an aircraft such as an aeroplane, helicopter, or jet is an airspeed limitation which is mainly selected by an aircraft designer.

Generally, at speeds higher or greater than the manoeuvring speed, aircraft pilots are advised not to attempt a full deflection of any flight control surface because it's capable of resulting in a damage to the structure of an aircraft.

If you're a pilot, to find the maneuvering speed of an aircraft, you should look at the flight manual of the aircraft or on the cockpit placard in the aircraft. The maneuvering speed of an aircraft is a calibrated speed and should not be exceeded by any pilot.

A rectangular wing, as compared to other wing planforms, has a tendency to stall first at the wingtips.

This is due to the fact that the air flowing over the wing's upper surface at the tips has a shorter distance to travel than the air flowing over the wing's lower surface.

This results in a higher pressure differential between the upper and lower surfaces at the tips, which can cause the airflow to separate from the wing and result in a stall.
Additionally, rectangular wings typically have a lower aspect ratio, which means that the wing is shorter and wider compared to other wing planforms.

This can also contribute to the tendency for the wingtips to stall first, as the shorter wingspan reduces the amount of lift generated by the wing, which can result in a higher angle of attack and ultimately a stall.
