I applied via LinkedIn and was interviewed in Sep 2023. There were 3 interview rounds.
Pumps are mechanical devices used to move fluids from one place to another by creating a flow.
Pumps are used in various industries such as water treatment, oil and gas, and manufacturing.
They can be classified into different types based on their mechanism, such as centrifugal pumps and positive displacement pumps.
Examples of pumps include water pumps in households, fuel pumps in vehicles, and industrial pumps for large
Different types of pump casings include volute, diffuser, axial flow, and mixed flow casings.
Volute casing: Most common type, converts kinetic energy into pressure.
Diffuser casing: Increases the efficiency of the pump by slowing down the flow and converting velocity energy into pressure.
Axial flow casing: Used in pumps with high flow rates and low head.
Mixed flow casing: Combines features of both radial and axial flow
Net Positive Suction Head (NPSH) is a measure of the pressure available at the suction port of a pump to prevent cavitation.
NPSH is important for ensuring that a pump operates efficiently and does not experience cavitation.
It is calculated by subtracting the vapor pressure of the liquid from the total suction head.
NPSH is typically provided by the pump manufacturer and must be greater than the required NPSH for the pum...
Cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure, which can cause damage to equipment.
Cavitation occurs when the pressure of a liquid drops below its vapor pressure, causing bubbles to form and collapse rapidly.
It can occur in pumps, propellers, and valves, leading to erosion and damage to the equipment.
To prevent cavitation, ensure proper design and maintenance of equipment, ma...

Pumps and aerators are used to move fluids and gases respectively.
Pumps work by creating a pressure difference to move fluids from one place to another.
Aerators introduce air into liquids to increase oxygen levels and promote biological processes.
Types of pumps include centrifugal, positive displacement, and jet pumps.
Types of aerators include surface aerators, diffused aerators, and mechanical aerators.

Desalination is the process of removing salt and other minerals from seawater to make it suitable for drinking or irrigation.
Desalination can be done through processes like reverse osmosis, distillation, and electrodialysis.
Reverse osmosis involves forcing seawater through a membrane to separate salt from water.
Distillation involves heating seawater to create steam, which is then condensed back into water, leaving the ...
Reverse osmosis is a water purification process that uses a partially permeable membrane to remove ions, molecules, and larger particles from drinking water.
Reverse osmosis works by applying pressure to a concentrated solution to force water molecules through a semipermeable membrane, leaving behind contaminants.
The process helps remove impurities such as salt, minerals, and other particles from water, making it suitab...

Type V cement is typically used in sulfate-rich water due to its high resistance to sulfate attack.
Type V cement is specially formulated to resist sulfate attack
It has a low heat of hydration and high resistance to chemical attack
Examples of Type V cement include Portland cement and blended hydraulic cements
A pile is a long, slender column typically made of concrete or steel used to support structures like buildings or bridges.
Piles are driven into the ground to transfer loads from the structure to the soil below.
They are commonly used in construction projects where the soil is not strong enough to support the weight of the structure.
Examples of where piles are used include building foundations, bridges, and retaining wal
