Seinumero Nirman Quality Engineer Interview Questions, Process, and Tips

Types of pumps include centrifugal, reciprocating, and rotary pumps.

• Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.

• Reciprocating pumps use a piston or diaphragm to move fluid through a system.

• Rotary pumps use rotating mechanisms to displace fluid, such as gear, vane, and screw pumps.

Types of flow include laminar flow, turbulent flow, and transitional flow.

• Laminar flow: smooth and orderly flow with parallel layers of fluid moving in the same direction.

• Turbulent flow: chaotic and irregular flow with mixing of fluid particles in all directions.

• Transitional flow: a mix of laminar and turbulent flow, often occurring during a transition phase.

• Examples: Laminar flow in a straight pipe, turbulent flow in

CNC stands for Computer Numerical Control, a technology used in manufacturing processes to control machining tools and 3D printers.

• CNC machines are programmed using a code called G-code, which controls the movement and operation of the machine.

• CNC machines can be used for cutting, milling, drilling, and other manufacturing processes.

• CNC machines offer high precision and repeatability in production.

• Examples of CNC machi...read more

Throttle governing controls flow rate by adjusting the size of the opening, while nozzle governing controls flow rate by changing the pressure at the nozzle outlet.

• Throttle governing involves adjusting the size of the opening through which the fluid flows, controlling the flow rate.

• Nozzle governing involves changing the pressure at the nozzle outlet to control the flow rate.

• Throttle governing is commonly used in carbur...read more

CNC stands for Computer Numerical Control and is a general term for a system that controls the functions of a machine tool. VMC stands for Vertical Machining Center and is a specific type of CNC machine used for milling operations.

• CNC is a general term for any machine tool controlled by a computer, while VMC specifically refers to a vertical milling machine.

• VMC machines are typically used for milling operations, while ...read more
