Q1. How turbine works
Ans. 
A turbine works by converting the kinetic energy of a fluid or gas into mechanical energy to generate power.
• Turbines have blades that are rotated by the fluid or gas passing through them

• The rotating blades are connected to a shaft which drives a generator to produce electricity

• There are different types of turbines such as steam turbines, gas turbines, and wind turbines

Q2. Draw Stress and Strain graph for ductile materials
Ans. 
Stress-strain graph for ductile materials shows a linear elastic region followed by plastic deformation until fracture.
• Elastic region: linear relationship between stress and strain

• Yield point: point where plastic deformation begins

• Plastic deformation: material undergoes permanent deformation without increase in stress

• Necking: reduction in cross-sectional area before fracture

• Fracture: final failure of the material

Q2. What is meant by distillation & its types?
Ans. 
Distillation is a process of separating components of a mixture based on their boiling points.
• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used for separating liquids with a large difference in ...read more

Q4. How to calculate no of trays in the distillation column?
Ans. 
To calculate no of trays in distillation column, use McCabe-Thiele method or Fenske equation.
• Determine the desired purity of the distillate

• Calculate the number of theoretical trays using McCabe-Thiele method or Fenske equation

• Account for efficiency and other factors to determine actual number of trays needed

Q5. What is meant by affinity law?
Ans. 
Affinity law relates to the relationship between flow rate, pressure, and speed of a pump.
• Affinity law states that the flow rate of a pump is directly proportional to its speed.

• It also states that the pressure generated by a pump is proportional to the square of its speed.

• Affinity law is used to predict the performance of a pump at different speeds.

• For example, if a pump is running at 50% of its maximum speed, the flow...read more

Q6. What is required to increase the flow rate in a centrifugal pump?
Ans. 
To increase flow rate in a centrifugal pump, increase impeller speed, reduce discharge head, or increase impeller diameter.
• Increase impeller speed by adjusting motor speed or using a larger motor

• Reduce discharge head by opening valves or reducing pipe friction

• Increase impeller diameter by replacing impeller or using a pump with a larger impeller

• Ensure pump is properly primed and not clogged

• Consider the limitations of t

Q7. How is the Vacuum pump operated?
Ans. 
A vacuum pump is operated by creating a vacuum in a closed system to remove air or gas molecules.
• The pump creates a low-pressure area in the system, causing air or gas to be drawn in and removed.

• There are different types of vacuum pumps, including rotary vane pumps, diaphragm pumps, and scroll pumps.

• The pump may be powered by electricity, compressed air, or a hand crank.

• Vacuum pumps are used in a variety of industries,...read more
