a pitot tube measures a dynamic pressure of 540 pa. find the corresponding velocity of air in m/s, V=__m/s

Answers

Answer 1

A pitot tube measures a dynamic pressure of 540 so the corresponding velocity of air in m/s, V=23.5 m/s.

To determine the corresponding velocity of air in m/s, we can use the Bernoulli's equation which relates the dynamic pressure to the velocity of the fluid.

The equation is expressed as: P + 0.5ρ[tex]V^2[/tex] = constant, where P is the static pressure, ρ is the density of the fluid, and V is the velocity.

We assume that the static pressure is equal to atmospheric pressure, which is approximately 101,325 Pa.

Solving for V, we get V = [tex]\sqrt{(2*(540))/1.225)}[/tex] = 23.5 m/s. Therefore, the velocity of air in m/s is approximately 23.5 m/s.

Answer 2

To find the corresponding velocity of air (V) in m/s, we can use the formula for dynamic pressure:

Dynamic pressure (q) = 0.5 * air density (ρ) * air velocity (V)²

We are given the dynamic pressure (q) as 540 Pa. For air at standard conditions, we can use an approximate air density (ρ) of 1.225 kg/m³. We need to solve for air velocity (V).

Rearrange the formula to solve for V:

V² = (2 * q) / ρ
V = √((2 * q) / ρ)

Now, plug in the given values:

V = √((2 * 540 Pa) / 1.225 kg/m³)
V = √(1080 / 1.225)
V ≈ 30.06 m/s

The corresponding air velocity (V) is approximately 30.06 m/s.

Determine the angular impulse from the change in angular momentum b. Apply the impulse-momentum theorem to determine the Torque EVALUATE THE ANSWER Is the unit of torque correct? ______________________________________________________________ Is the magnitude of the torque realistic? _____________________________________________________

Answers

Answer:

Explanation:

Li = 8.9 kg m² /s , Lf = 0

Time = Δt = 5.2 s

Angular impulse = change in angular momentum = Li - Lf

= 8.9 - 0 = 8.9 kg.m²/s .

Average torque = angular impulse / time

= 8.9 / 5.2 = 1.711  kg m² / s²

Li = 8.9 kg m² /s , Lf = 0

Δt = 5.2 s

unit of torque = force x distance = mass x acceleration x distance

= kg . m /s² x m

= kg m² / s²

Una pieza de platino metalico con densidad 21.5 g/cm3 tiene un volumen de 4.49 cm3. Cual es su masa

Answers

Answer:

m = 96.53 grams

Explanation:

Given that,

The density of metallic platinum, d = 21.5 g/cm³

Volume, V = 4.49 cm³

We need to find the mass. Let it is m. We know that the density is equal to the mass per unit volume. So,

[tex]d=\dfrac{m}{V}\\\\m=d\times V\\\\m=21.5\times 4.49\\\\m=96.53\ g[/tex]

So, the required mass is 96.53 grams.

If you choose to go old school, obviously you get an actual photo that can be stored physically. This means it is a memory that can be preserved, and it might feel more nostalgic being able to touch the photo.

On the other hand, a digitally stored photo can be altered (photoshop), but it is forever as long as the internet still exists. A physical photo would fade with time, which doesn't happen with a digital photo.

It is definitely easier to argue that digital photography has more advantages (they do, it is why nobody uses film anymore)

Points you can consider:

Can be transferred to the other side of the world instantly

Ability to make copies and print as many photos as you want

Can be stored on cloud/devices and be like that forever

Compare them with film photography to give a more solid response.

What is gravitational potential energy?

Gravitational potential energy is energy an object possesses because of its position in a gravitational field.

It is given by P.E = mgh

where m = mass

g= acceleration due to gravity

h = height of the object

Here,

h = 1.45km  = 1450 m

P.E = 3.36 x [tex]10^{9}[/tex] J

g = 9.8m/[tex]s^{2}[/tex]

therefore, m = P.E/ gh = (3.36 x [tex]10^{9}[/tex]s J)/ 9.8 x 1450

m = 2.36 x [tex]10^{5}[/tex]

Hence mass of the airplane is 2.36 x [tex]10^{5}[/tex]

What is the gpe of a rock weighing 100N that is sitting on top pf a hill 300 m high?

Answers

Answer:

Gpe = 30000J

Explanation:

Given the following data;

Weight = 100N

Height = 300m

To find the gravitational potential energy (gpe);

Gravitational potential energy can be defined as an energy possessed by an object or body due to its position above the earth surface.

Mathematically, potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where,

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Gpe = mgh

But weight = mg = 100N

Substituting into the equation, we have:

Gpe = 100*300

Gpe = 30000J

The magnitude of the acceleration is 1.6 m/s².

Explanation:

We can find the magnitude of the acceleration by using the following equation:

[tex] x_{f} = x_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]

Where:

[tex] x_{f}[/tex]: is the final position = 80 m

[tex] x_{0[/tex]: is the initial position = 0

[tex] v_{0}[/tex]: is the initial speed = 0 (it starts from rest)

a: is the acceleration =?

t: is the time = 10 s

Hence, the acceleration is:

[tex] a = \frac{2x_{f}}{t^{2}} = \frac{2*80 m}{(10 s)^{2}} = 1.6 m/s^{2} [/tex]

Therefore, the magnitude of the acceleration is 1.6 m/s².
