In the fully developed region of flow in a circular pipe, does the velocity profile change in the flow direction?

Engineering
1 answer:
taurus [48]3 years ago
3 0

Answer:

<em>No, the velocity profile does not change in the flow direction.</em>

Explanation:

In a fluid flow in a circular pipe, the boundary layer thickness increases in the direction of flow, until it reaches the center of the pipe, and fill the whole pipe. If the density, and other properties of the fluid does not change either by heating or cooling of the pipe, <em>then the velocity profile downstream becomes fully developed, and constant, and does not change in the direction of flow.</em>

As you recall, the Logic Schematic for Lab2&amp;3 (‘Smart ECC Transportation ‘Bus’ with Robotic Arm: 4-Bit Microcomputer) was ve
Thepotemich [5.8K]

Answer:

Explanation:

In the first instance, you had a logic function, which you had derived using some sort of a truth table, then reduced it using K-maps, and finally derived the simplified logic. If you had used logic gates to implement the logic, the result would have been the fact that there were a lot of logic gates used. For example, for a function of 2 variables, we would need 4 AND gates and 1 OR gate. Thus, the resulting circuitry would have looked very complex.

Whereas, if you would use a microcontroller to implement the logic, all you need would be a piece of code to run the logic. There would either be minimum number of gates (or no gates at all, depending on the logic you wanted to implement).

Thus the microcontroller would make the circuit look a lot less complex. Making the design and texting simpler and since there are now fewer components to test. Microcontrollers is that on the same piece of silicon, you could embed a lot more complex logic or program, than using purely digital gates this is another good that comes with Microcontrollers.

A 179 ‑turn circular coil of radius 3.95 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicu
suter [353]

Answer:

The energy, that is dissipated in the resistor during this time interval is 153.6 mJ

Explanation:

Given;

number of turns, N = 179

radius of the circular coil, r = 3.95 cm = 0.0395 m

resistance, R = 10.1 Ω

time, t = 0.163 s

magnetic field strength, B = 0.573 T

Induced emf is given as;

emf= N\frac{d \phi}{dt}

where;

ΔФ is change in magnetic flux

ΔФ  = BA = B x πr²

ΔФ  = 0.573 x π(0.0395)² = 0.002809 T.m²

emf = N\frac{d \phi}{dt} = 179(\frac{0.002809}{0.163} ) = 3.0848 \ V

According to ohm's law;

V = IR

I = V / R

I = 3.0848 / 10.1

I = 0.3054 A

Energy = I²Rt

Energy = (0.3054)² x 10.1 x 0.163

Energy = 0.1536 J

Energy = 153.6 mJ

Therefore, the energy, that is dissipated in the resistor during this time interval is 153.6 mJ
