Bernoulli's Principle states that for an incompressible, non-viscous fluid, the increase in the speed of the fluid occurs simultaneously with a decrease in pressure or potential energy. The principle is fundamental to fluid dynamics and is applied in various engineering systems such as airfoils and venturis.

Darcy's Law describes the flow of a fluid through a porous medium, with the flow rate being proportional to the pressure drop and the permeability of the medium. This law is essential for understanding filtration, soil mechanics, and petroleum engineering.

Henry's Law quantifies the amount of gas that will dissolve in a liquid at a given temperature, stating that the amount of gas dissolved is directly proportional to its partial pressure above the liquid. This is important for gas-liquid equilibrium studies and for understanding carbonation in beverages.

The Joule-Thomson Effect describes the temperature change of a real gas or liquid when it is forced through a valve or porous plug while kept insulated so that no heat is exchanged with the environment. This is important for the liquefaction of gases and refrigeration processes.

The Gibbs Phase Rule, expressed as $F = C - P + 2$, where $F$ is the degrees of freedom, $C$ is the number of components, and $P$ is the number of phases, provides the number of independent variables that can be changed without altering the number of phases. This principle is important for the study of phase equilibrium and the phase behavior of mixtures.

The Van der Waals Equation is a modified ideal gas law that accounts for the volume of gas particles and the intermolecular forces between them, represented as $P = \frac{nRT}{V-nb} - \frac{an^2}{V^2}$. This equation is crucial for understanding the behavior of real gases, especially under high pressure and low temperature.

Fick's First Law relates the diffusive flux to the concentration gradient, suggesting that substances move from areas of high concentration to low concentration, while Fick's Second Law predicts how diffusion causes the concentration to change over time. These laws are fundamental to understanding mass transfer processes in chemical engineering.

Le Chatelier's Principle states that if an external change is applied to a system at equilibrium, the system will adjust in a way that counteracts the change. This is important for predicting how conditions like pressure, temperature, and concentration will affect chemical reactions in industrial processes.

Gay-Lussac's Law states that for a given mass and constant volume of an ideal gas, the pressure is directly proportional to its temperature. This is significant in predicting how gas pressure changes with temperature in closed systems.

Dalton's Law of Partial Pressures states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of individual gases. This law is key to understanding the behavior of gas mixtures and is used in gas collection and analysis techniques.

Raoult's Law states that the vapor pressure of an ideal solution is directly proportional to the mole fraction of solvent present in the solution. This law is important for determining the vapor pressure and boiling points of solutions in distillation processes.

The Arrhenius Equation, $k = A e^{-E_a/(RT)}$, describes how reaction rates increase with temperature due to an exponential increase in the number of molecules that have sufficient energy to react. Key for understanding reaction kinetics and the effect of temperature on reaction speed.

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. It is fundamental to chemical engineering for ensuring mass balance in processes and designing reaction systems.

The Nernst Equation, given by $E = E^0 - (RT/nF) \ln(Q)$, relates the cell potential to the standard electrode potential, temperature, and reaction quotient. It's essential for electrochemical systems, such as batteries and corrosion studies, to predict cell potential under non-standard conditions.
