The hunting of alternators is defined as the oscillation of the generator frequency that occurs as a result of a momentary fluctuation in the power supply or an unexpected load variation.

In this case, the frequency of the power generated by the alternator is not maintained at a steady level. Hunting of the alternator is a common issue that occurs when an electrical generator is installed in an isolated network. Alternators are used to generate alternating current (AC) that is used in various applications. In general, the hunting of alternators is usually caused by unbalanced loads or incorrect system configurations. The hunting of an alternator is an undesirable phenomenon that results in the alternator generating a frequency that is higher or lower than the rated frequency. To prevent hunting of an alternator, it is recommended that the electrical load is balanced and the system configuration is checked. In addition, a voltage regulator can be used to control the voltage supplied to the system.The motoring of alternators refers to the operation of the electrical generator as a motor. In this case, an electrical current is supplied to the alternator to turn the rotor, which then generates a magnetic field that interacts with the stator windings to produce a torque that drives the rotor. The motoring of alternators is used in applications where the generator is used as a motor, such as in the starting of gas turbines. In such cases, the generator is connected to the turbine shaft and is used to start the turbine by turning the rotor. In general, the motoring of an alternator is the opposite of the generation of electrical power, in which the rotor is turned by a mechanical force to generate electrical power. Therefore, the motoring of an alternator is used to convert electrical energy into mechanical energy, whereas the generation of electrical power converts mechanical energy into electrical energy.

Answer:

a) -505.229 kJ/Kg

b) -1.724 kJ/kg

Explanation:

T1 = 400°C

P1 = 3 MPa

P2 = 125 kPa

work output   = 530 kJ/kg

surrounding temperature = 20°C = 293 k

A) Calculate heat transfer from Turbine to surroundings

Q = h2 + w - h1

h ( enthalpy )

h1 = 3231.229 kj/kg

enthalpy at P2

h2 = hg = 2676 kj/kg

back to equation 1

Q = 2676 + 50 - 3231.229  = -505.229 kJ/Kg  ( i.e.  heat is lost )

b) Entropy generation

entropy generation = Δs ( surrounding )  + Δs(system)

                                =  - 505.229 / 293   + 0

                                = -1.724 kJ/kg

When cutting in an orthogonal direction, the tool's cutting edge faces the direction of the workpiece's relative motion. False

Lines that form right angles or are perpendicular are referred to as orthogonal, as in This design contains many orthogonal elements. The term "orthographic" has been used to describe this. When two parallel lines intersect or come together, they form a right angle. A generalisation of perpendicularity in geometry is the idea of orthogonality in mathematics. By extension, the partitioning of specific system features is referred to as "orthogonality." The phrase has particular uses in other fields as well, like painting and chemistry. Two vectors are said to be orthogonal if they are perpendicular to one another. In other words, the dot product of the two vectors is zero.

Discharge in a stream usually increase downstream because the volume of water in the stream increases with distance from the source and the main reason of flowing downward is phenomena of gravity and also because stream velocities increase with distance from the source.

What is a Stream and How does it works?

A stream is a body of water that flows on the surface of the Earth. The terms stream and river are frequently used interchangeably, though rivers typically describe larger streams.

Streams require gravity and water to exist. When precipitation falls on the ground, some of it trickles into groundwater, but the majority of it runs downhill as runoff and collects in streams. A watershed, also known as a drainage basin, is the area where water is collected for a stream. Smaller streams frequently merge to form larger streams as they flow downhill. These smaller streams are referred to as tributaries.

Answer:

I think its True

it should be True

This question is incomplete, the missing diagram is uploaded along this answer below.

Answer:

the forces required to keep the artery in place is 1.65 N

Explanation:

Given the data in the question;

Inlet velocity V₁ = 50 cm/s = 0.5 m/s

diameter d₁ = 15 mm = 0.015 m

radius r₁ = 0.0075 m

diameter d₂ = 11 mm = 0.011 m

radius r₂ = 0.0055 m

A₁ = πr² = 3.14( 0.0075 )² =  1.76625 × 10⁻⁴ m²

A₂ = πr² = 3.14( 0.0055 )² =  9.4985 × 10⁻⁵ m²

pressure at inlet P₁ = 110 mm of Hg = 14665.5 pascal

pressure at outlet P₂ = 95 mm of Hg = 12665.6 pascal

Inlet volumetric flowrate = A₁V₁ = 1.76625 × 10⁻⁴ × 0.5 = 8.83125 × 10⁻⁵ m³/s

given that; blood density is 1050 kg/m³

mass going in m' = 8.83125 × 10⁻⁵ m³/s × 1050 kg/m³ = 0.092728 kg/s

Now, using continuity equation

A₁V₁ = A₂V₂

V₂ = A₁V₁ / A₂ = (d₁/d₂)² × V₁

we substitute

V₂ =  (0.015 / 0.011 )² × 0.5

V₂ = 0.92975 m/s

from the diagram, force balance in x-direction;

0 - P₂A₂ × cos(60°) + Rₓ = m'( V₂cos(60°) - 0 )    

so we substitute in our values

0 - (12665.6 × 9.4985 × 10⁻⁵)  × cos(60°) + Rₓ = 0.092728( 0.92975 cos(60°) - 0 )    

0 - 0.6014925 + Rₓ =  0.043106929 - 0

Rₓ = 0.043106929 + 0.6014925

Rₓ = 0.6446 N

Also, we do the same force balance in y-direction;

P₁A₁ - P₂A₂ × sin(60°) + R\(_y\) = m'( V₂sin(60°) - 0.5 )  

we substitute

⇒ (14665.5 × 1.76625 × 10⁻⁴) - (12665.6 × 9.4985 × 10⁻⁵) × sin(60°) + R\(_y\) = 0.092728( 0.92975sin(60°) - 0.5 )

⇒ 1.5484 + R\(_y\) = 0.092728( 0.305187 )

⇒ 1.5484 + R\(_y\) = 0.028299    

R\(_y\) = 0.028299 - 1.5484

R\(_y\) = -1.52 N

Hence reaction force required will be;

R = √( Rₓ² + R\(_y\)² )

we substitute

R = √( (0.6446)² + (-1.52)² )

R = √( 0.41550916 + 2.3104 )

R = √( 2.72590916 )

R = 1.65 N

Therefore, the forces required to keep the artery in place is 1.65 N

In order to write the given expression as a decimal, we can simplify the expression and then evaluate it.

The given expression can be simplified as follows:$$
\begin{aligned}
\(\frac 15 \left(\frac 15\right)^2 \left(\frac 15\right)^3 \left(\frac 15\right)^4 &= \frac{1}{5^1} \cdot \frac{1}{5^2} \cdot \frac{1}{5^3} \cdot \frac{1}{5^4}\\\)
\(&= \frac{1}{5^{1+2+3+4}}\\\)
\(&= \frac{1}{5^{1+2+3+4}}\\\)
\(&= \frac{1}{9,765,625}\)
\end{aligned}
$$Now, we can evaluate the given expression by dividing 1 by 9,765,625 as follows:$$
\begin{aligned}
\(\frac{1}{9,765,625} &= \frac{1}{10,000,000 - 234,375}\\\)
\(&= 0.\overline{000}1\\&= 1 \cdot 10^{-7}\)
\(\end{aligned}$$Therefore, $\frac 15 \left(\frac 15\right)^2 \left(\frac 15\right)^3 \left(\frac 15\right)^4$ as a decimal is $1 \cdot 10^{-7}$\), which means that the decimal is a very small number.

The view factor F12 between two parallel planes of infinite extent can be determined using the view factor relations and the results for opposing parallel planes.

To develop the expression for the view factor F12 between the parallel planes, we start with the equation F12 = (A1 / A2) * (1 - F21), which relates the view factor between two surfaces to the areas and the view factor from the second surface to the first surface. In the case of opposing parallel planes, the view factor F21 is equal to F12.

We substitute this value into the equation to obtain F12 = 1 - F21. By substituting F21 = 1 - (1 / (2 * π * r)), where r is the distance between the planes, we simplify the expression for F12. The resulting expression is F12 = 1 / (2 * π * r), indicating that the view factor between the parallel planes is inversely proportional to the distance between them and depends only on geometric considerations.

As the damping ratio and frequency increase, the proportional and derivative gains of a control system also need to be adjusted accordingly to maintain stability and optimal performance.

When the damping ratio and frequency increase, the proportional gain and derivative gain of a control system also tend to increase. This is because a higher damping ratio and frequency imply that the system is more responsive to changes in input signals. To maintain stability and prevent oscillations, the control system needs to respond quickly to these changes, which requires a higher proportional gain. Additionally, a higher derivative gain is necessary to ensure that the system responds appropriately to changes in the rate of change of the input signal.

True, in an ink-jet printer, the printhead mechanism contains ink-filled cartridges.

The printhead is the component of the printer that sprays tiny droplets of ink onto the paper to create the printed image. In an ink-jet printer, the printhead moves back and forth across the paper, depositing ink droplets in precise patterns to form text and images.

Most ink-jet printers use two types of ink cartridges: one for black ink and one for color ink. Some printers may use separate cartridges for each color in order to provide more precise color control.

The ink in the cartridges is typically a liquid that contains water, colorants, and other chemicals that help to improve print quality and prevent clogs in the printhead. When the printer is in use, the ink is heated and forced through tiny nozzles in the printhead, where it is sprayed onto the paper in precise patterns.
