Bearings are mechanical components that allow for smooth rotation or linear motion between two parts.
Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.
Ball bearings use balls to reduce friction between two surfaces.
Roller bearings use cylindrical rollers to support radial and axial loads.
Plain bearings have a sliding surface instead of balls or rollers.
Fluid bearings use a thi...

There are two main types of pumps: centrifugal pumps and positive displacement pumps.
Centrifugal pumps work by converting rotational kinetic energy into hydrodynamic energy to move fluid.
Positive displacement pumps use a mechanism to repeatedly expand and contract a cavity to move fluid.
Examples of centrifugal pumps include water pumps in cars, while examples of positive displacement pumps include piston pumps in hydra

There are various types, sizes, and names of parts used in mechanical maintenance engineering.
Types of parts include bearings, gears, belts, valves, and pumps.
Sizes of parts can range from small screws to large engines.
Names of parts can vary depending on the specific machine or equipment being maintained.
Examples of specific parts include ball bearings, spur gears, V-belts, gate valves, and centrifugal pumps.
Material difference refers to the variation in properties and characteristics of different materials used in engineering.
Materials can differ in their strength, durability, conductivity, and other properties.
The choice of material depends on the specific application and the desired outcome.
For example, steel is often used in construction due to its strength and durability, while copper is used in electrical wiring due ...

I applied via Recruitment Consultant and was interviewed before Apr 2020. There were 4 interview rounds.
The power of a pump can be calculated using the formula: Power = (Flow rate x Head) / Efficiency
The power of a pump is determined by the flow rate, head, and efficiency
Flow rate is the volume of fluid passing through the pump per unit time
Head is the height difference between the inlet and outlet of the pump
Efficiency is the ratio of the actual power output to the power input
The formula to calculate power is: Power = (...
Air flow in HVAC ducting can be calculated using the formula Q = AV
Q = air flow rate in cubic feet per minute (CFM)
A = cross-sectional area of the duct in square feet
V = air velocity in feet per minute (FPM)
Air velocity can be measured using a pitot tube or an anemometer
Duct sizing and layout can affect air flow and should be considered in calculations
A reactor can be installed by following a few steps.
Choose a suitable location for the reactor
Prepare the foundation for the reactor
Install the reactor vessel and associated equipment
Connect the piping and electrical systems
Test the reactor for proper functioning
Commissioning of a reactor involves a series of tests and procedures to ensure safe and efficient operation.
Pre-commissioning checks and inspections
Functional testing of equipment and systems
Testing of safety systems
Fuel loading and reactor startup
Performance testing and optimization
Final acceptance testing
Documentation and training
Regulatory approval
Examples: Pressurized Water Reactor (PWR), Boiling Water Reactor (BWR
Condensers are used to convert high-pressure vapor into liquid form.
Condensers are used in various industries such as power plants, refrigeration systems, and chemical processing plants.
They help in increasing the efficiency of the system by reducing the pressure and temperature of the vapor.
They also help in recovering valuable materials from the vapor, such as water in a power plant.
Examples of condensers include she...
