Answer:
(b)False
Explanation:
Given:
Prandtl number(Pr) =1000.
We know that 
Where
is the molecular diffusivity of momentum
is the molecular diffusivity of heat.
Prandtl number(Pr) can also be defined as

Where
is the hydrodynamic boundary layer thickness and
is the thermal boundary layer thickness.
So if Pr>1 then hydrodynamic boundary layer thickness will be greater than thermal boundary layer thickness.
In given question Pr>1 so hydrodynamic boundary layer thickness will be greater than thermal boundary layer thickness.
So hydrodynamic layer will be thicker than the thermal boundary layer.
The all purpose one will work or you could use type C I believe.
Answer: Contaminants can cause tremendous harm to a population; not only humans but entire local animal species can be devastated by poisonous drinking water. Crops and livestock can also be affected. Citizens can make prudent choices regarding natural resources and energy use. Scientists can research and create products that can reduce or eliminate unnecessary waste and pollution.
Explanation:
Answer :
<h3>Flow rate in pipe B is = 0.3094

</h3>
Explanation:
Given :
Length of pipe A
m
Length of pipe B
m
Flow rate through pipe A 
Diameter of pipe
m
Velocity from pipe A,



Here, head loss is same because height is same.




Now rate of flow from pipe B is,
