Jindal Stainless Diploma Trainee Engineer Interview Questions and Answers for Freshers
6 Interview questions
Enthalpy is a thermodynamic property that represents the total heat content of a system.
Enthalpy is denoted by the symbol H.
It is defined as the sum of the internal energy of a system and the product of its pressure and volume.
The formula for enthalpy is H = U + PV, where U is the internal energy, P is the pressure, and V is the volume.
Enthalpy is often used in chemical reactions to measure the heat exchanged with...
Laws governing energy and its transformations in physical systems.
First law: Energy cannot be created or destroyed, only transferred or converted.
Second law: Entropy of an isolated system always increases over time.
Third law: Absolute zero cannot be reached by any finite number of processes.
Applications in engineering, physics, chemistry, and biology.
Examples include heat engines, refrigeration, and combustion pro...
Slider crank mechanism is a simple mechanism used to convert rotary motion into reciprocating motion.
Consists of a slider, crank, connecting rod and a shaft
Used in engines, pumps, compressors, etc.
The slider moves back and forth in a straight line
The crank rotates in a circular motion
The connecting rod connects the slider and the crank
The shaft provides the rotary motion
The mechanism is used to convert the recipro...
Degree of freedom refers to the number of independent variables that can be varied in a system without changing its state.
Degree of freedom is important in engineering and physics.
It helps in understanding the behavior of a system.
It is calculated as the difference between the number of variables and the number of constraints.
For example, a ball rolling on a flat surface has two degrees of freedom - forward/backwa...
Bernoulli's theorem states that as the speed of a fluid increases, its pressure decreases.
The theorem is based on the conservation of energy in a fluid system.
It is commonly used in fluid dynamics to calculate the pressure and velocity of fluids in motion.
The theorem is applicable to both incompressible and compressible fluids.
An example of Bernoulli's theorem in action is the lift generated by an airplane wing.
Th...
Entropy is a measure of disorder or randomness in a system.
Entropy is denoted by the symbol S.
The formula for entropy is S = k ln W, where k is the Boltzmann constant and W is the number of possible microstates.
Entropy increases with an increase in the number of microstates.
Entropy is a state function and is independent of the path taken to reach a particular state.
Entropy has units of J/K (joules per kelvin).
