The component of a regenerative vapor power cycle that permits only liquid to pass through to a region of lower pressure is a Valve/trap.

<h3>What is vapor?</h3>

In physics, a substance in the gas phase at a temperature lower than its critical temperature is referred to as a vapor or vapor.
This means that the vapor can be condensed to a liquid by increasing the pressure on it without decreasing the temperature.
An aerosol is distinct from a vapor.
A suspension of minute liquid, solid, or both types of particles in a gas is known as an aerosol.

<h3>Why does vapor form?</h3>

Evaporation or sublimation are two processes that can be used to create it.
Unlike clouds, fog, or mist, which are only suspended drops of liquid water in the atmosphere, watevaporur is a gas and cannot be seen.
In the atmosphere, water vapor frequently exists below the boiling point.

answer :

c) G(s) = 100 / ( s + 100 )

d) y'(t) + 100Y(s) = 100 X(s)

e) g(t) = e^-100t u(t)

Explanation:

a) Sketch the bode plot

The filter here is a low pass filter

b) Sketch the s-plane

attached below. pole ( s ) is at 100

c) write the transfer function of the filter

Transfer function ; G(s) = 100 / ( s + 100 )

d) write the differential equation

Y(s) / X(s) = 100 / s + 100

Y(s) [ s + 100 ] = 100 X(s)

= sY(s) + 100Y = 100 X(s)

∴ differential equation = y'(t) + 100Y(s) = 100 X(s)

e) write out the unforced transient response

g(t) = e^-100t u(t)

f) write out the frequency response

Can you determine the critical distance along a flat surface?

Keith_Richards [23]

Explanation:

Consider a fluid of density, ρ moving with a velocity, U over a flat plate of length, L.

Let the Kinematic viscosity of the fluid be ν.

Let the flow over the fluid be laminar for a distance x from the leading edge.

Now this distance is called the critical distance.

Therefore, for a laminar flow, the critical distance can be defined as the distance from the leading edge of the plate where the Reynolds number is equal to 5 x $10^{5}$

And Reynolds number is a dimensionless number which determines whether a flow is laminar or turbulent.

Mathematically, we can write,

Re = $\frac{\rho .U.x}{\mu }$

or 5 x $10^{5}$ = $\frac{\rho .U.x}{\mu }$ ( for a laminar flow )

Therefore, critical distance

$x=\frac{5\times 10^{5}\times \mu }{\rho \times U}$

So x is defined as the critical distance upto which the flow is laminar.

ivolga24 [154]

Answer:

Option (C)

Explanation:

A tool is usually defined as an equipment or a device that is hold by the hands and is used to carry out a particular function. For example, a hammer is a tool that is used to hit on a hard surface.

A tool can be considered as a technology under a certain condition, such as the applications of this objects are helpful in solving a practical problem, with ease and comfortability.

Thus, the correct answer is option (C).
