Mechanical Interview Q&A: ATD/HT/EME

Applied Thermodynamics/Heat Transfer/EME

How many laws of thermodynamics are there?

There are three laws of the thermodynamics
What is the importance of the thermodynamics in the field of mechanical engineering?
State law of conservation of energy?
what is second law of thermodynamics?
what is third law of thermodynamics?
Define Overall Heat transfer coefficient?

All the mechanical engineering systems are studied with the help of thermodynamics. Hence it is very important for the mechanical engineers.

According to the laws of conservation of energy, “energy can neither be created nor be destroyed. It can only be transformed from one form to another.”

The entropy of the universe increases over time and moves towards a maximum value.
