Biesse Manufacturing Interview Questions, Process, and Tips

Types of valves and SI unit of pressure are important concepts in mechanical engineering.

• Types of valves include gate, globe, ball, butterfly, and check valves.

• SI unit of pressure is Pascal (Pa).

• Other units of pressure include bar, psi, and atm.

• Valves are used to control the flow of fluids in pipelines and machinery.

• Different types of valves are used for different applications and operating conditions.

The least count of screw gauge is the smallest measurement that can be read on the instrument.

• It is the difference between the pitch of the screw and the distance between two consecutive graduations on the circular scale.

• It is usually expressed in millimeters or fractions of millimeters.

• The least count of a screw gauge can vary depending on the instrument's design and purpose.

• For example, a micrometer screw gauge used ...read more

Cylinders are mechanical devices used for storing and transporting gases or liquids.

• There are two main types of cylinders: gas cylinders and hydraulic cylinders.

• Gas cylinders are used for storing compressed gases, such as oxygen, nitrogen, and propane.

• Hydraulic cylinders are used for generating force through the use of hydraulic fluid.

• Other types of cylinders include pneumatic cylinders, which use compressed air, and r...read more
