Wood Group Principal Process Engineer Interview Questions and Answers

An orifice meter is a device used to measure the flow rate of a fluid through a pipe by measuring the pressure drop across a constriction in the pipe.

• It consists of a flat plate with a hole in the center, placed perpendicular to the flow of fluid.

• The pressure drop across the orifice is proportional to the square of the flow rate.

• It is commonly used in industries such as oil and gas, chemical, and water treatment.

• Orific...read more

Control valve sizing is done based on the process requirements and the characteristics of the fluid being controlled.

• Determine the required flow rate and pressure drop

• Select the appropriate valve type and style

• Calculate the valve size based on the flow coefficient (Cv) and the valve authority

• Consider factors such as noise, cavitation, and erosion

• Verify the selected valve can handle the process conditions and fluid prop
