The phase velocity of transverse waves in a crystal of atomic separation a is given byy = csin(ka/2) pka/2 1. What is the disper

damaskus [11]

Answer:

a

e(k) = \frac{2a}{c} * sin (\frac{k*a}{2} )

b

G_{v} = \frac{d e(k ) }{dk } = \frac{a^2}{c} * cos (\frac{k* a}{2} )

Explanation:

From the question we are told that

The velocity of transverse waves in a crystal of atomic separation is

$b_y = c \frac{sin (\frac{k*a}{2} )}{\frac{k*a}{2} }$

Generally the dispersion relation is mathematically represented as

$e(k) = b_y * k$

=> $e(k) = c \frac{sin(\frac{k*a}{2} ) }{ \frac{k*a}{2} } * k$

=> $e(k) = c * \frac{sin (\frac{k_a}{2} )}{ \frac{a}{2} }$

=> $e(k) = \frac{2a}{c} * sin (\frac{k*a}{2} )$

Generally the group velocity is mathematically represented as

$G_{v} = \frac{d e(k ) }{dk } = \frac{a^2}{c} * cos (\frac{k* a}{2} )$

Water at 20oC flows through a long elliptical duct 30 cm wide and 22 cm high. What average velocity, in m/s, would cause the wei

mars1129 [50]

Explanation:

The given data is as follows.

Fluid is water so, density $\rho = 1000 kg/m^{3}$

Weight flow rate = 500 lbf/s = 2224.11 N/sec

Cross-sectional area (A) = $\pi \times \frac{30}{2} \times \frac{22}{2}$

= 0.05184 $m^{2}$

Hence, weight flow rate will be given as follows.

w = $\rho \times g \times A \times V$

2224.11 N/sec = $\rho \times g \times A \times V$

V = $\frac{2224.11}{1000 \times 9.81 \times 0.05184}$ m/s

= 4.373 m/s

Thus, we can conclude that average velocity in the given case is 4.373 m/s.
