The reason 316 stainless steel is used for cryogenic applications instead of 430 stainless steel is due to its higher resistance to corrosion and better mechanical properties at low temperatures.

The problem with using molybdenum for high-temperature applications like turbine blades in aircraft engines is its crystal structure. Molybdenum has a body-centered cubic (BCC) crystal structure, which tends to be more brittle at low temperatures and prone to embrittlement at high temperatures, reducing its effectiveness as a material for such applications.

If the grain size of a steel sample was reduced, the brittle-to-ductile temperature would likely decrease. This is because reducing the grain size increases the number of grain boundaries, which impedes the movement of dislocations within the material. This, in turn, can enhance the material's ductility and make it less prone to brittle failure at lower temperatures.

The correct option is D,  the energy of the highest filled state defines the Fermi energy.

In a solid formed from a large number of atoms, the energy of the highest occupied state at absolute zero temperature is referred to as the Fermi energy.

This energy level separates the filled states from the empty states and represents the maximum energy that an electron in the material can have at absolute zero temperature.

The Fermi energy is typically located close to the center of the bandgap between the valence and conduction bands in the solid.

d) The energy of the highest filled state defines the Fermi energy. The Fermi energy is the energy level at which the probability of finding an electron is exactly 0.5. In a solid formed from a large number of atoms, the Fermi energy corresponds to the energy level of the highest occupied state in the valence band, since all lower energy levels in the valence band are filled with electrons.

The Fermi energy corresponds to the energy level of the highest filled state in a solid at absolute zero temperature, also known as the Fermi level. This energy level is located in the middle of the energy gap between the filled valence band and the empty conduction band, and it determines the electrical and thermal properties of the material.

Option (d) correctly identifies the energy level of the highest filled state as defining the Fermi energy, while options (a), (b), and (c) are incorrect. The energy of the highest unoccupied state in the conduction band is not the Fermi energy, but rather the energy required to excite an electron from the highest filled state to the conduction band. The energy of the ground state of the conduction band and the center of the conduction band are also not equivalent to the Fermi energy, as they do not take into account the occupied electron states below the energy gap.

Answer:

a) 50 J/kg

b) 721 67 KW

Explanation:

The velocity of the wind v = 10 m/s

diameter of the blades d = 70 m

efficiency of the turbine η = 30%

density of air ρ = 1.25 kg/m^3

The area of the blade A = \(\pi d^2/4\)

A = \(\frac{3.142 * 70^2}{4}\) = 3848.95 m^2

The mechanical energy air per unit mass is gives as

e = \(v^2/2\) = \(\frac{10^2}{2}\) = 50 J/kg

Theoretical Power of the turbine P = ρAve

where

ρ is the density of air

A is the area of the blade

v is the velocity of the wind

e is the energy per unit mass

substituting values, we have

P = 1.25 x 3848.95 x 10 x 50 = 2405593.75 W

Actual power = ηP

where η is the efficiency of the turbine

P is the theoretical power of the turbine

Actual power = 0.3 x 2405593.75 = 721678.1 W

When a diode is impartial, the dynamic resistance could be significant.

Non-ohmic materials' resistance is measured using dynamic resistance. The ratio of a differential change in voltage to a differential change in current is how it is defined.

A forward biased diode's I-V characteristic can be used to define the dynamic resistance. The ratio of a minor change in voltage to a little change in current, or Temperature has a direct correlation with the diode's dynamic resistance.

For a non-ohmic conductor, dynamic resistance is an independent variable that depends on the current (or voltage) flowing through the material.

A forward biased diode's I-V characteristic can be used to define the dynamic resistance.

The velocity of a river is directly proportional to its discharge and inversely proportional to its cross-sectional area. Therefore, if two rivers have the same depth and discharge, the one with the smaller cross-sectional area will have a greater velocity.

In this case, Stream B is half as wide as Stream A, which means it has a smaller cross-sectional area. Therefore, Stream B will have a greater velocity than Stream A. To visualize this, imagine two rivers with the same depth and discharge, but one is a mile wide while the other is only half a mile wide. The narrower river will have a much stronger current because the same amount of water is being funneled through a smaller space.
In conclusion, the velocity of a river is determined by both its depth and cross-sectional area. When two rivers have the same depth and discharge, the one with the smaller cross-sectional area will have a greater velocity. In this case, Stream B is half as wide as Stream A, so Stream B will have the greater velocity.

Modern petrol engines employ ignition coils in all ignition systems for the same fundamental purpose: to produce the high voltage necessary to ignite a spark at the spark plug.

An electric spark is used in a gasoline engine's ignition system to start the fuel-air combination, which burns in the cylinders to create the motive force.

A storage battery, an induction coil, a device to timing high-voltage discharges from the induction coil, a distributor, and a set of spark plugs are the essential parts of the ignition system. The mechanism converts the low voltage electric current from the storage battery, which is typically 12 volts, to high voltage (some 40,000 volts). The distributor sends the high-voltage pulses in succession to each spark plug in the firing order.

The statement "Venturi meters and nozzles work on similar principles of discharge measurement" is True statement.

Venturi meters and nozzles are devices used to measure fluid flow rates based on Bernoulli's equation.

They both use a constriction in the flow path to create a pressure drop, which is then used to calculate the flow rate of the fluid. The difference between them is in the shape of the constriction.

Venturi meters have a gradual constriction that gradually increases in diameter, while nozzles have a sharp constriction that abruptly reduces the diameter of the flow path.

Venturi meters are more suitable for measuring fluids that are more viscous or have a higher flow rate, while nozzles are more suitable for measuring high-velocity fluids.

Therefore the statement is True.

When an ordinarily elastic material cracks brittlely, there is little or no outward trace of material deformation prior to failure.

The plastic deformation that occurs before failure is minimal or nonexistent in brittle fractures. Glasses, ceramics, as well as various polymers and metals, frequently fracture in a brittle way.

When a material is exposed to forces below its yield limit, brittle fractures take place. A ductile material is typically the foundation for machine design, and the design criteria are intended to prevent plastic and, in some circumstances, elastic deformations.

Material that has undergone either no plastic deformation or very little plastic deformation prior to fracture is said to have fractured with brittleness. Since they all share this quality, brittle materials include rock, concrete, glass, and cast iron.
