Relative humidity is the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature.

• Relative humidity is expressed as a percentage.

• It is an important factor in weather forecasting and climate studies.

• High relative humidity can make the air feel warmer than it actually is, while low relative humidity can make the air feel cooler.

• For example, if the relative humidit...read more

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - used in HVAC systems, Positive displacement pump - used in hydrau...read more

Extractive distillation is a process used to separate components of a liquid mixture by adding a solvent that preferentially removes one component.

• Involves adding a solvent to the mixture to enhance separation

• Solvent selectively removes one component from the mixture

• Used when normal distillation is not effective in separating components

The elastic modulus of steel is a measure of its stiffness and ability to withstand deformation under stress.

• The elastic modulus of steel is typically around 200 GPa (Gigapascals).

• It is a material property that describes the ratio of stress to strain in a material.

• Steel is known for its high elastic modulus, which allows it to resist bending and stretching.

• The elastic modulus of steel can vary depending on factors such...read more
