I applied via Campus Placement and was interviewed in Nov 2023. There was 1 interview round.
Stress and strain are measures of the internal forces within a material. Stress is the force applied per unit area, while strain is the deformation of the material.
Stress is the force applied per unit area on a material, measured in units like Pascals or pounds per square inch.
Strain is the deformation or change in shape of a material due to stress, measured as a ratio of the change in length to the original length.
Str...
Fatigue failure is the weakening and eventual breaking of a material under repeated or fluctuating stress.
Occurs due to repeated or fluctuating stress on a material
Can lead to cracks, fractures, or complete failure
Common in metal structures like bridges, aircraft, and machinery
Static loads do not change with time, while dynamic loads involve at least one changing parameter. Fatigue failure occurs when a body is subjected to continuous dynamic loading.
Static loads have constant force magnitude, direction, and point of application
Dynamic loads involve changes in at least one of the load parameters over time
Fatigue failure occurs when a body is subjected to continuous dynamic loading, leading t...
NPSH of a pump stands for Net Positive Suction Head, which is a measure of the pressure available at the suction port of the pump.
NPSH is important for determining if a pump will operate properly without cavitation.
It is calculated by subtracting the vapor pressure of the fluid from the total suction head of the pump.
NPSH is typically provided by the pump manufacturer and must be greater than the required NPSH for the

Heat transfer coefficient changes with baffle spacing in heat exchangers. Other important factors include fluid properties, flow rate, and surface roughness.
Heat transfer coefficient increases with decreasing baffle spacing
Fluid properties such as viscosity and thermal conductivity affect heat transfer
Higher flow rates can increase heat transfer coefficient
Surface roughness can affect heat transfer by creating turbulen
Viscosity Index of lube measures its resistance to change in viscosity with temperature.
Viscosity Index (VI) is an important property of lubricating oils.
It measures the oil's ability to maintain its viscosity under different temperature conditions.
Higher VI means the oil's viscosity changes less with temperature, indicating better performance.
VI is calculated using kinematic viscosity measurements at two different tem...
Different kinds of distillation include simple distillation, fractional distillation, steam distillation, and vacuum distillation.
Simple distillation is used to separate liquids with different boiling points.
Fractional distillation is used to separate liquids with similar boiling points.
Steam distillation is used to extract essential oils from plants.
Vacuum distillation is used to separate liquids with high boiling poi...

Gibbs free energy is called free energy because it is the energy available to do work at constant temperature and pressure.
Gibbs free energy is the maximum amount of work that can be obtained from a system at constant temperature and pressure.
It takes into account both the enthalpy and entropy of a system.
If the Gibbs free energy is negative, the reaction is spontaneous and can do work.
Examples include the combustion o...
Maxwell's equations describe the behavior of electromagnetic fields.
There are four equations: Gauss's law, Gauss's law for magnetism, Faraday's law, and Ampere's law with Maxwell's addition.
Together, these equations explain how electric and magnetic fields interact and propagate through space.
Maxwell's equations are fundamental to the study of electromagnetism and have many practical applications, such as in the design...
