Answer:

Explanation:
Given that
Lattice constant = a
Radius of unit cell cell =R
Atom is in BCC structure.
In BCC unit cell (Body centered cube)
1.Eight atoms at eight corner of cube which have 1/8 part in each cube.
2.One complete atom at the body center of the cube
So the total number of atoms in the BCC
Z= 1/8 x 8 + 1 x 1
Z=2
In triangle ABD



In triangle ABC

AC=4R
BC=a

So


So the relationship between lattice constant and radius of unit cell

Answer:
V=33.66 m/s

Re>4000, The flow is turbulent flow.
Explanation:
Given that
Pressure difference = 50 mm of Hg
We know that density of Hg=136000
ΔP= 13.6 x 1000 x 0.05 Pa
ΔP=680 Pa
Diameter of tunnel = 200 mm
Property of air at 25°C
ρ=1.2
Dynamic viscosity

Velocity of fluid given as


V=33.66 m/s
Reynolds number



Re>4000,So the flow is turbulent flow.
