Q1. Different between kinematics and dynamic viscosity
Ans. 
Kinematic viscosity is the ratio of dynamic viscosity to density, representing the fluid's resistance to flow. Dynamic viscosity is the measure of a fluid's internal resistance to flow.
• Kinematic viscosity is dynamic viscosity divided by density

• Kinematic viscosity is measured in square meters per second (m^2/s)

• Dynamic viscosity is measured in pascal-seconds (Pa.s) or centipoise (cP)

• Dynamic viscosity represents the fluid...read more

Q2. Working principle of fluid machine application
Ans. 
Fluid machines apply the principles of fluid mechanics to generate, transmit, and control power.
• Fluid machines use fluids to transfer energy, such as pumps, turbines, and compressors.

• They operate based on the principles of conservation of mass, momentum, and energy.

• Examples include hydraulic pumps in cars, wind turbines, and water turbines in hydroelectric power plants.

Q1. What is the second law of thermodynamics?
Ans. 
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
• Entropy in a closed system tends to increase over time

• Heat energy naturally flows from hot to cold objects

• Efficiency of energy conversion processes is limited by the second law of thermodynamics

Q2. What is the difference between creep and fatigue?
Ans. 
Creep is the slow, time-dependent deformation of a material under constant load, while fatigue is the weakening of a material due to repeated loading and unloading.
• Creep is a time-dependent phenomenon, while fatigue is a cyclic phenomenon.

• Creep occurs at high temperatures and constant stress, while fatigue occurs at lower temperatures and varying stress levels.

• Creep leads to permanent deformation, while fatigue can lea...read more

Q3. What is thermocouple?
Ans. 
A thermocouple is a temperature sensor that consists of two different metals joined together at one end, which produces a voltage proportional to the temperature difference between the junction and the other end.
• Consists of two different metals joined together at one end

• Produces a voltage proportional to the temperature difference

• Commonly used in industrial applications for temperature measurement

Q4. What is t-t-t diagram?
Ans. 
T-t-t diagram is a time-temperature-transformation diagram used in materials science to understand the transformation of phases in a material.
• T-t-t diagram shows the relationship between time, temperature, and the transformation of phases in a material.

• It helps in predicting the microstructure of a material based on the cooling rate and temperature.

• T-t-t diagrams are commonly used in metallurgy to understand the phase

Q5. What is annealing?
Ans. 
Annealing is a heat treatment process used to soften metals and increase their ductility.
• Annealing involves heating a metal to a specific temperature and then slowly cooling it to room temperature.

• This process helps to relieve internal stresses, improve machinability, and enhance electrical conductivity.

• Examples of metals that are commonly annealed include steel, copper, and aluminum.

Q6. What is the critical temperature of steel?
Ans. 
The critical temperature of steel is the temperature at which it loses its magnetic properties.
• The critical temperature of steel is around 770°C (1420°F).

• Above this temperature, steel becomes non-magnetic and undergoes a phase change.

• The critical temperature varies depending on the type of steel and its composition.
