Darcy's law is a formula used to describe the flow of fluids through porous media.

• Darcy's law states that the flow rate of a fluid through a porous medium is directly proportional to the pressure drop and the permeability of the medium, and inversely proportional to the viscosity of the fluid.

• It is commonly used in hydrogeology to calculate groundwater flow.

• The formula is Q = -KA(dP/dL), where Q is the flow rate, K is ...read more

Materials can be qualified based on their physical, mechanical, chemical, and thermal properties.

• Qualify materials based on physical properties such as density, hardness, and color.

• Consider mechanical properties like strength, elasticity, and toughness.

• Examine chemical properties such as reactivity, corrosion resistance, and stability.

• Evaluate thermal properties including conductivity, expansion coefficient, and meltin
