Q1. What are the tensile forces acts on material
Ans. 
Tensile forces are forces that stretch or pull materials apart.
• Tensile forces act in the opposite direction of compressive forces

• Examples of tensile forces include stretching a rubber band or pulling on a rope

• Tensile strength is a measure of a material's ability to withstand tensile forces

Q3. Laws of thermodynamics
Ans. 
The fundamental laws of thermodynamics govern the behavior of energy in systems.
• First Law of Thermodynamics: Energy cannot be created or destroyed, only transferred or converted.

• Second Law of Thermodynamics: The entropy of an isolated system will always increase over time.

• Third Law of Thermodynamics: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• Examples: A car engine conve...read more

Q4. What is Fouriers Law write its equation
Ans. 
Fourier's Law describes the flow of heat through a material.
• Fourier's Law states that the rate of heat transfer through a material is directly proportional to the negative gradient of temperature and the area perpendicular to the direction of heat flow.

• The equation for Fourier's Law is q = -k * A * (dT/dx), where q is the heat transfer rate, k is the thermal conductivity of the material, A is the cross-sectional area, ...read more

Q6. Stress Strain Curve Explain
Ans. 
The stress-strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• The curve typically consists of three main regions: elastic deformation, plastic deformation, and fracture.

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

• The plastic region is where permanent deformation occurs, but the mater...read more

Q8. How to Calculate velocity of fluid flowing through pipe
Ans. 
Velocity of fluid flowing through a pipe can be calculated using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
• Calculate the cross-sectional area of the pipe using the formula A = π * r^2, where r is the radius of the pipe.

• Determine the flow rate (Q) of the fluid, which is typically measured in cubic meters per second (m^3/s) or liters per...read more

Q9. What is Difference between entropy and enthalpy
Ans. 
Entropy is a measure of disorder or randomness in a system, while enthalpy is a measure of the heat energy in a system.
• Entropy is a thermodynamic property that measures the amount of energy in a system that is not available to do work.

• Enthalpy is a thermodynamic property that measures the total heat content of a system.

• Entropy increases in irreversible processes, while enthalpy remains constant.

• Entropy is denoted by S,...read more

Q10. Draw Refrigeration Cycle Graph
Ans. 
The Refrigeration Cycle graph shows the process of cooling a space by transferring heat from inside to outside.
• The cycle starts with the refrigerant entering the compressor as a low-pressure gas.

• The refrigerant is compressed, raising its temperature and pressure, before entering the condenser where it releases heat to the surroundings.

• After losing heat, the refrigerant becomes a high-pressure liquid and flows into the ...read more
