Answer:

Environmental chemistry and analytical chemistry

Explanation:

Environmental chemistry is a scientific study of chemical species in the environment as well as the cycle of materials in nature. Broadly speaking, environmental chemistry involves the study of the sources, reactions, transport, and fates of chemical species in the environment.

Analytical chemistry is a branch of chemistry that deals with the development and use of tools and methods to carry out investigation into the nature and composition of chemical substances.

Both environmental chemistry and analytical chemistry are involved when you collect soil samples for the purpose of analysis. A work focused on environmental clean up must first be concerned with the fate of species in the environment (environmental chemistry) as well as the identification of various contaminants in the environment (analytical chemistry). Hence the answer.

How is the partial pressure of a gas in a mixture calculated?

In-s [12.5K]

The total pressure of a mixture of gases can be defined as the sum of the pressures of each individual gas: Ptotal=P1+P2+…+Pn. + P n . The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas.

Your boss tells you that water at 68 F is flowing in a cooling tower loop at a rate of 600 gpm, in an 8-inch inside diameter pip

avanturin [10]

Explanation:

The volumetric flow rate of water will be as follows.

q = $600 gpm \times \frac{0.000063 m^{3} s^{-1}}{1 gpm}$

= 0.0378 $m^{3}/s
$

Diameter = $8 in \times \frac{0.0254 m}{1 in}$

= 0.2032 m

Relation between area and diameter is as follows.

A = $\frac{\pi}{4} \times D^{2}$

= $\frac{3.14}{4} \times (0.2032 m)^{2}$

= 0.785 x 0.2032 x 0.2032

= 0.0324 $m^{2}$

Also, q = A × V

or, V = $\frac{q}{A}$

= $\frac{0.0378 m^{3}/s}{0.0324 m^{2}}$

= 1.166 m/s

As, viscosity of water = 1 cP = $10^{-3}$ Pa-s

Density of water = 1000 $kg/m^{3}$

Therefore, we will calculate Reynolds number as follows.

Reynolds number = $\frac{D \times V \times density}{viscosity}$

= $\frac{0.2032 m \times 1.166 m/s \times 1000}{10^{-3}}$

= 236931.2

Hence, the flow will be turbulent in nature.

Thus, we can conclude that the Reynolds number is 236931.2 and flow is turbulent.
