Q1. What is relative humidity
Ans. 
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

Q2. Types of pumps?
Ans. 
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

Q3. Extractive distillation means?
Ans. 
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

Q3. What is enthalpy in thermodynamics?
Ans. 
Enthalpy is the sum of internal energy and pressure-volume work done by a system.
• Enthalpy is a thermodynamic property of a system.

• It is represented by the symbol 'H'.

• It is defined as the sum of internal energy and pressure-volume work done by a system.

• Enthalpy change is given by the formula ΔH = ΔU + PΔV.

• It is used to measure the heat content of a system at constant pressure.

• Enthalpy is important in chemical reactions ...read more

Q4. What is coupling and explain
Ans. 
Coupling refers to the degree of interdependence between two components in a system.
• Coupling is a measure of how closely connected two components are in a system.

• It can be classified as tight coupling or loose coupling.

• Tight coupling means that the components are highly dependent on each other, while loose coupling means that they are more independent.

• Coupling can affect the maintainability, scalability, and flexibilit...read more
