Explanation:
The given data is as follows.
Diameter of pipe, D = 0.01 m
Velocity V = 0.03 m/s
Fluid density = 36.4 
Viscosity = 0.651 Pa-s
Formula to calculate Reynold number is as follows.
Re = 
= 
= 0.01677
Since, Re < 2100. This means that the flow is laminar.
So, for laminar flow in pipes,
Darcy friction factor f = 
= 
= 3816
Thus, we can conclude that the Darcy friction factor value is 3816.
Answer:
Air is less dense on a mountaintop than at sea level.
Air pressure is lower at low altitudes.
As you climb a mountain, air pressure increases.
More force pushes on the air at the bottom of an air column.
As you descend a mountain, air molecules are closer together.

Find moles:
<span>36.0 g of glucose divided by 180 g/mol = 0.200 moles of glucose </span>
<span>find molarity: </span>
<span>0.200 moles of glucose / 2 litres = 0.100 Molar solution </span>
This solute-solvent interaction will release energy into the surroundings and makes the beaker warm.
<u>Explanation:</u>
The sulfuric acid is dissolved in water and it formed a solvation sphere of water molecules around the sulphur ions. So on stirring the beaker is getting warm. As the beaker is getting warm, this means the reaction occuring between sulfuric acid and water is exothermic reaction.
And so the energy is released into the surroundings. The energy released came from the breaking of bonds of sulfuric acid, as the acid is getting dissociated in water.
So, the release of energy in the surroundings lead to the warming of the beaker. Hence, the solute-solvent interaction release energy into the surroundings.
False - the amount of inertia depends on the MASS of the object; the heavier it is, the slower it is, and the lighter it is, the faster it is.
