I applied via Campus Placement and was interviewed before Dec 2021. There were 2 interview rounds.
Types of maintenance include preventive, predictive, corrective, and proactive maintenance.
Preventive maintenance involves regular inspections and maintenance to prevent breakdowns.
Predictive maintenance uses data and analytics to predict when equipment will need maintenance.
Corrective maintenance is performed after a breakdown has occurred to restore equipment to working condition.
Proactive maintenance involves identi...

I applied via Campus Placement and was interviewed in Aug 2021. There were 3 interview rounds.
I applied via Campus Placement and was interviewed before Jul 2021. There were 3 interview rounds.
Different parts of pumps include impeller, casing, shaft, bearings, and seals.
Impeller: rotates to create suction and discharge pressure
Casing: contains the impeller and directs the flow of fluid
Shaft: connects the impeller to the motor
Bearings: support the shaft and reduce friction
Seals: prevent fluid from leaking out of the pump

Pressure and velocity compounding are methods used to increase the efficiency of steam turbines.
Pressure compounding involves dividing the pressure drop across the turbine into smaller stages, each with its own set of moving blades.
Velocity compounding involves dividing the steam flow into smaller streams, each flowing through a set of fixed blades.
Both methods increase the efficiency of the turbine by reducing the amo...
Iron-iron carbide diagram is a graphical representation of the phases of iron and carbon at different temperatures and compositions.
Also known as the Fe-C diagram
Shows the transformation of iron from ferrite to austenite to pearlite
Used to determine the microstructure and properties of steel
Helps in designing heat treatment processes for steel
Important tool for metallurgists and materials engineers
Normalizing, annealing, and hardening are heat treatment processes used to alter the properties of metals.
Normalizing involves heating the metal to a temperature above its critical point and then cooling it in air. This process improves the strength and toughness of the metal.
Annealing involves heating the metal to a specific temperature and then cooling it slowly. This process reduces the hardness and increases the du...
Efficiency of Rankine cycle formula.
Efficiency = (Net work output / Heat input)
Efficiency = (1 - T2/T1)
T1 is the temperature of steam at the inlet of turbine
T2 is the temperature of steam at the outlet of turbine
Net work output = (P1 - P2) * (V2 - V1)
Heat input = m * (h1 - h2)
m is the mass flow rate of steam
h1 is the enthalpy of steam at the inlet of turbine
h2 is the enthalpy of steam at the outlet of turbine
