I applied via Campus Placement and was interviewed in Aug 2024. There were 2 interview rounds.
Hoop stresses in pipes are circumferential stresses that occur due to internal pressure, and their ratios are important for determining the safety of the pipe.
Hoop stress is calculated using the formula: P*D/2t, where P is the internal pressure, D is the diameter of the pipe, and t is the thickness of the pipe wall.
The ratio of hoop stress to longitudinal stress is important in determining the safety factor of the pipe...
Various materials used for pipe making include steel, copper, PVC, and HDPE.
Steel: commonly used for high-pressure applications
Copper: used for water supply lines
PVC: lightweight and corrosion-resistant, often used for drainage systems
HDPE: flexible and durable, suitable for underground piping

I applied via Walk-in and was interviewed in Sep 2023. There were 2 interview rounds.
P&ID of Pump System shows the piping, equipment, instrumentation, and control interlocks of the system.
Include pump symbol with arrows indicating flow direction
Label all equipment such as pumps, valves, tanks, etc.
Show instrumentation like pressure gauges, flow meters, etc.
Indicate control interlocks and safety features
Use standard symbols and colors as per industry guidelines
NPSH available stands for Net Positive Suction Head available, which is a measure of the absolute pressure at the suction port of a pump.
NPSH available is the total suction head in feet absolute at the suction nozzle of the pump.
It is important for ensuring that the pump does not cavitate, which can cause damage to the pump and decrease efficiency.
NPSH available is calculated by subtracting the vapor pressure of the li...
NPSH is calculated by subtracting the vapor pressure of the liquid from the total head of the pump.
NPSH = H - (Pv / rho * g)
H is the total head of the pump
Pv is the vapor pressure of the liquid
rho is the density of the liquid
g is the acceleration due to gravity
Ensure all units are consistent (e.g. meters, Pascal, kg/m^3, m/s^2)
A two-phase system P&ID shows the process flow of a system with two distinct phases.
Identify the two phases involved in the system (e.g. liquid-gas, solid-liquid).
Use different symbols to represent each phase on the P&ID.
Show the flow direction and connections between components in the system.
Include labels and legends to explain the components and their functions.
Ensure clarity and consistency in the representation of

Discussion on soil mechanics starting from modulus of elasticity to liquifaction
Modulus of elasticity is a measure of soil stiffness
Soil strength is important in determining its ability to withstand loads
Liquifaction occurs when soil loses strength and behaves like a liquid
Factors affecting soil strength include soil type, moisture content, and stress history
Liquifaction can lead to soil failure and damage to structure

Android architecture stack is a set of layers that make up the Android operating system.
The stack includes four main layers: Linux kernel, native libraries, Android runtime, and application framework.
The Linux kernel provides low-level system functionality.
Native libraries are written in C or C++ and provide access to hardware-specific features.
The Android runtime includes the Dalvik virtual machine and core libraries.

AIDL stands for Android Interface Definition Language, used for inter-process communication in Android.
AIDL is used to define the interface between client and service in Android.
It allows communication between different processes in Android.
AIDL is used to pass complex data types between processes.
AIDL is similar to Remote Procedure Call (RPC) in other programming languages.
Example: AIDL is used in Android to implement...
Hash set and hash map are data structures used to store key-value pairs for efficient retrieval.
Hash set stores unique values without any specific order.
Hash map stores key-value pairs and allows fast retrieval of values based on keys.
Both use hashing to map keys to their corresponding values.
In Java, HashSet and HashMap are implementations of these data structures.
