The answer is crystalline solid. Crystalline solids have a regular arrangement of particles, because of that, they possess definite geometry.
This means that if you take a look at the crystal under the microscope you would notice that there is a pattern that constantly repeats. This pattern is called a unit cell, and crystal is made up of stacked unit cells.
Answer:
(a) 21.44 ft/s
(b) 0 ft/s
(c) 19.51 ft/s
Explanation:
2 in = 2/12 ft = 0.167 ft
For steady laminar flow, the function of the fluid velocity in term of distance from center is modeled as the following equation:
where R = 0.167 ft is the pipe radius and is the constant fluid velocity at the center of the pipe.
We can integrate this over the cross-section area of the in order to find the volume flow
So the average velocity
b) At the wall of the pipe, r = R so
c) At a distance of 0.6 in = 0.6/12 = 0.05 ft
Answer:
Ts=51.83C
Explanation:
First we calculate the surface area of the cylinder, neglecting the top and bottom covers as indicated by the question
Cilinder Area= A=πDL
L=200mm=0.2m
D=20mm=0.02m
A=π(0.02m)(0.2m)=0.012566m^2
we use the equation for heat transfer by convection
q=ha(Ts-T)
q= heat=2Kw=2000W
A=Area=0.012566m^2
Ts=surface temperature
T=water temperature=20C
Solving for ts
Ts=q/(ha)+T
Ts=2000/(5000*0.012566m^2)+20=51.83C
Answer:
0.497
0.38806
Explanation:
According to the question normalizing data is done by
The normalized value at 3.8 cm is 0.497
We have the relation
Hence, the theoretically expected normalized value at 6.1 cm is 0.38806
Answer:
0.471Nm downwards.
Explanation:
For this problem we need to apply the Torque equation,
That is
Where N is the number of turns, A is the area, B is magnetic field and \theta is the angle loop mae with B
We calculate the area, so
Replacing in the equation of Torque,
We can conclude that the magnutide of maximum torque is 0.471Nm downwards.
