Answer:


Explanation:
Given that
Q= 5 L/min
1 L = 10⁻³ m³/s
1 min = 60 s
Q=0.083 x 10⁻³ m³/s
d= 6 μm
v= 1 mm/s
So the discharge flow through one tube
q = A v


A=2.8 x 10⁻¹¹ m²
v= 1 x 10⁻³ m/s
q= 2.8 x 10⁻¹⁴ m³/s
Lets take total number of tube is n
Q= n q
n=Q/q


Surface area A
A= π d L


Answer:
Since 2 pi = 360 deg and pi equals 180 deg, 30 deg = pi / 6.
S = theta * R = pi / 6 * 3 cm = 1.57 cm
Answer:
Shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes.
Answer:
Value of electric field along the axis and equitorial axis
and
respectively.
Explanation:
Given :
Distance between charges , 
Magnitude of charges , 
Dipole moment , 
Case A) (x,y) = (12.0 cm, 0 cm) :
Electric field of dipole in its axis ,

Putting all values and 
We get , 
Case B) (x,y) = (0 cm, 12.0 cm) :
Electric field of dipole on equitorial axis ,

Putting all values and
We get , 
Hence , this is the required solution.
