Q1. Explain about stress strain curve
Ans. 
The stress-strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• The curve typically consists of several distinct regions: elastic deformation, yield point, plastic deformation, and ultimate failure.

• In the elastic region, the material deforms elastically and returns to its original shape when the stress is removed.

• The yield point is where the material transi...read more

Q2. What are gears and types of gears
Ans. 
Gears are mechanical components used to transmit motion and power between rotating shafts. There are various types of gears including spur, helical, bevel, and worm gears.
• Gears are toothed mechanical components that mesh together to transmit motion and power.

• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have cone-shaped...read more

Q4. What do you mean by tolerance.
Ans. 
Tolerance refers to the allowable deviation from a specified dimension or value in engineering.
• Tolerance is important in manufacturing to ensure that parts fit together properly.

• It is typically specified as a range, such as +/- 0.1mm.

• Tolerance can be applied to dimensions, angles, surface finishes, and other characteristics.

• For example, a hole may have a tolerance of +/- 0.05mm to allow for variations in the drilling p

Q1. Explain performance curves of centrifugal pump
Ans. 
Performance curves of centrifugal pump show the relationship between flow rate, head, and efficiency.
• Performance curves show how a pump performs at different flow rates and heads.

• The curve typically includes lines for efficiency, power consumption, and NPSH requirements.

• The shape of the curve can indicate the pump's operating range and efficiency.

• Operating a pump outside of its recommended range can lead to issues like

Q2. Explain best efficency point of centrifugal pump
Ans. 
The best efficiency point of a centrifugal pump is the operating point where the pump achieves the highest efficiency.
• The best efficiency point is typically located near the pump's BEP (Best Efficiency Point) on the pump curve.

• At the best efficiency point, the pump operates with the least amount of energy consumption and highest output.

• Operating the pump away from the best efficiency point can lead to decreased efficie...read more

Q3. Explain joule Thomson effect
Ans. 
Joule Thomson effect is the change in temperature of a gas when it is allowed to expand without performing work.
• Occurs when a gas expands through a valve or porous plug

• No external work is done on or by the gas

• Temperature change depends on the gas properties and initial conditions

• Used in natural gas processing to cool the gas for further processing

Q5. Explain series and parallel operation of pumps
Ans. 
Series and parallel operation of pumps involve connecting multiple pumps together to achieve desired flow rates and pressures.
• In series operation, pumps are connected one after the other to increase the total head or pressure that the system can deliver.

• In parallel operation, pumps are connected side by side to increase the total flow rate that the system can deliver.

• Series operation is used when high pressure is requi...read more
