SAI Consulting Engineers Assistant Bridge Engineer Interview Questions and Answers

Types of compressors include reciprocating, rotary, centrifugal, and axial compressors.

• Reciprocating compressors use pistons to compress air or gas.

• Rotary compressors use rotating mechanisms such as screws or vanes.

• Centrifugal compressors use a rotating impeller to create centrifugal force.

• Axial compressors use rotating blades to compress air in a straight line.

• Examples include reciprocating air compressors, rotary scr...read more

The procedure to install centrifugal axial compressors involves proper planning, alignment, assembly, and testing.

• Ensure proper foundation is prepared to support the compressor

• Align the compressor with the piping system for proper flow

• Assemble the compressor components according to manufacturer's instructions

Pumps capacity refers to the maximum flow rate a pump can handle.

• Pumps capacity is typically measured in gallons per minute (GPM) or liters per minute (LPM).

• It is important to consider the required flow rate when selecting a pump for a specific application.

• Factors such as pump size, motor power, and system pressure affect the capacity of a pump.

• For example, a centrifugal pump may have a capacity of 500 GPM, while a dia
