What is the value of the thickness of the boundary layer at leading edge of the plate?

Physics
1 answer:
Harman [31]2 years ago
7 0

Along the flow direction, the boundary layer's thickness varies. For ReT values between 260 and 780, the boundary layer thickness—defined as the depth at which the normalized concentration has a value of 1/e—ranges between 800 and 250 m.

<h3>What is the Boundary layer?</h3>
  • A boundary layer is the thin layer of fluid that forms immediately around a bounded surface in physics and fluid mechanics as a result of the fluid flowing along the surface.
  • A no-slip boundary condition is created as a result of the fluid and wall interaction (zero velocity at the wall).
  • After that, the flow velocity above the surface steadily rises until it reaches the bulk flow velocity again.
  • The term "velocity boundary layer" refers to the thin layer of fluid whose velocity has not yet recovered to that of the main flow.
<h3>What purpose does a boundary layer serve?</h3>
  • Because it is on the fluid's boundary, engineers refer to this layer as the boundary layer.
  • Many aerodynamics issues, such as wing stall, skin friction drag on an object, and the heat transfer that takes place in high-speed flight, depend heavily on the specifics of the flow within the boundary layer.

Momentum is usually not exactly conserved in a real world demonstration of momentum conservation. What is a possible reason for
Maksim231197 [3]

Answer:

For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

A square, single-turn coil 0.132 m on a side is placed with its plane perpendicular to a constant magnetic field. An emf of 27.1
marta [7]

Answer:

0.35 T

Explanation:

Side, a = 0.132 m, e = 27.1 mV = 0.0271 V, dA / dt = 0.0785 m^2 / s

Use the Faraday's law of electromagnetic induction

e = rate of change of magnetic flux

Let b be the strength of magnetic field.

e = dФ / dt

e = d ( B A) / dt

e = B x dA / dt

0.0271 = B x 0.0785

B = 0.35 T

The function h = -t2 + 95 models the path of a ball thrown by a boy where h represents height, in feet, and t represents the tim
Evgesh-ka [11]

Answer:

A building where the boy is on the 12 floor

Explanation:

The equation of the height or position takes into account the initial conditions.

So the general equation is

x(t) = at+c

When you solve with the initial conditions t=0 you will find the position at the begining, so this is c the constant.

in our initial equation we have 95 as the constant. and this is a equation to find height so the initial height is 95feets.

Now a common building has a distance of 7.5 feet between every floor.

You divide 95 by 7.5 and you will find 12.6
