Steam turbine converts thermal energy in steam into mechanical energy.
Steam enters the turbine and expands, causing the rotor to spin
The spinning rotor is connected to a generator, producing electricity
Used in power plants, refineries, and other industrial applications
Impulse turbine efficiency is the ratio of actual work output to the theoretical work input, typically ranging from 70-90%.
Impulse turbine efficiency is calculated as the ratio of actual work output to the theoretical work input.
It is typically in the range of 70-90%, depending on the design and operating conditions of the turbine.
Factors affecting impulse turbine efficiency include blade design, nozzle efficiency, and...
The obsolete angle of impulse turbine is the angle at which the blades are set in relation to the direction of the water flow.
Obsolete angle is typically around 20-22 degrees for impulse turbines.
It determines the efficiency and performance of the turbine.
Incorrect angle can lead to reduced power output and efficiency.
Examples: Pelton wheel, Turgo turbine.
Blade efficiency of impulse turbine is typically around 80-90%.
Blade efficiency is a measure of how effectively the blades of a turbine convert the kinetic energy of the fluid into mechanical energy.
It is calculated as the ratio of the actual work done by the blades to the work that would be done if the fluid were to expand isentropically.
Blade efficiency for impulse turbines is generally higher than reaction turbines,...
The efficiency of an impulse turbine is typically around 70-90%.
Efficiency is calculated as the ratio of actual work output to the theoretical work input.
Impulse turbines have high efficiency due to the fact that the energy transfer occurs in stages.
Efficiency can be affected by factors such as blade design, operating conditions, and maintenance.
Examples of impulse turbines include Pelton wheel and Turgo turbine.
I applied via Walk-in and was interviewed before Aug 2023. There were 3 interview rounds.
45 minutes, moderate level questions
Types of pumps include centrifugal, reciprocating, rotary, and diaphragm pumps. Each pump is used for specific purposes based on its design and capabilities.
Centrifugal pumps are commonly used for water and sewage systems.
Reciprocating pumps are suitable for high-pressure applications like hydraulic systems.
Rotary pumps are used for viscous fluids like oils and chemicals.
Diaphragm pumps are ideal for handling corrosive
Otto cycle is used in gasoline engines while diesel cycle is used in diesel engines.
Otto cycle is a constant volume cycle while diesel cycle is a constant pressure cycle.
In Otto cycle, fuel-air mixture is ignited by a spark plug while in diesel cycle, fuel is injected into the combustion chamber at high pressure.
Otto cycle has a higher thermal efficiency compared to diesel cycle.
Examples of engines using Otto cycle inc...

I applied via Campus Placement and was interviewed in Nov 2020. There were 3 interview rounds.
Motor's principal refers to the basic operating principle of an electric motor.
Electric motors work on the principle of electromagnetic induction.
They convert electrical energy into mechanical energy.
The basic components of a motor include a stator, rotor, and commutator.
Examples of motors include AC motors, DC motors, and brushless motors.
The controller is a device that manages the operation of a system or machine by receiving input and sending output signals.
Controls the operation of a system or machine
Receives input signals
Sends output signals
Regulates and coordinates the functions of different components
Examples: temperature controller in HVAC system, speed controller in a motor
