Q1. What is FEM in your project
Ans. 
FEM stands for Finite Element Method, a numerical technique used to solve complex engineering problems by dividing them into smaller elements.
• FEM is a numerical technique used to analyze structures and systems by dividing them into smaller elements and solving equations for each element.

• It is commonly used in structural analysis, heat transfer, fluid dynamics, and other engineering fields.

• FEM helps in predicting how a ...read more

Q2. Tell me about mechanical machines
Ans. 
Mechanical machines are devices that use mechanical power to perform work, such as moving, lifting, cutting, or shaping materials.
• Mechanical machines convert mechanical energy into useful work

• They consist of moving parts like gears, levers, pulleys, and belts

• Examples include engines, pumps, conveyor belts, and cranes

Q2. . different forces acting on a moving cycle and force analysis . newtonian and non newtonian fluids .why tyres are made of rubber and not steel
Ans. 
Forces acting on a moving cycle, Newtonian vs non-Newtonian fluids, and why tires are made of rubber.
• Forces on a moving cycle include friction, air resistance, and gravity.

• Newtonian fluids have constant viscosity, while non-Newtonian fluids change viscosity with stress.

• Tires are made of rubber for flexibility, grip, and shock absorption.

• Rubber tires provide better traction and a smoother ride compared to steel tires.

Q3. Howadiabatic and constant volume processes are achieved in practical
Ans. 
Adiabatic and constant volume processes are achieved in practical by controlling heat transfer and volume change respectively.
• Adiabatic process is achieved by insulating the system to prevent heat transfer with the surroundings.

• Constant volume process is achieved by using a closed container where the volume remains constant during the process.

• Examples include adiabatic compression in a gas turbine engine and constant v

Q4. Why priming is neede in the pumps
Ans. 
Priming is needed in pumps to remove air and create a vacuum, ensuring proper functioning and preventing damage.
• Priming removes air from the pump, allowing it to create a vacuum and start pumping efficiently.

• It helps prevent cavitation, which can damage the pump by causing vibrations and erosion.

• Priming is essential for self-priming pumps to start pumping without manual intervention.

• Examples of priming methods include ...read more

Q5. What is NPSH of pumps
Ans. 
NPSH stands for Net Positive Suction Head, it is a measure of the pressure available at the suction port of a pump.
• NPSH is important for determining if a pump will operate properly without cavitation.

• It is calculated by subtracting the vapor pressure of the liquid being pumped from the total suction head of the pump.

• NPSH is typically provided by the pump manufacturer and must be considered when selecting a pump for a s
