Deep Industries Interview Questions, Process, and Tips

Line sizing is calculated based on the flow rate, pressure drop, and fluid properties.

• Determine the required flow rate for the process

• Calculate the pressure drop based on the length of the line and the fluid properties

• Select a pipe size that can handle the required flow rate and pressure drop

• Consider factors such as corrosion, erosion, and velocity limitations

• Use industry standards and guidelines for pipe sizing

• Perform...read more

Relief valves are of two types - pressure relief valves and safety relief valves. Their size is calculated based on the flow rate and pressure.

• Pressure relief valves are used to protect equipment from overpressure and are typically set at a specific pressure level.

• Safety relief valves are used as a last line of defense and are typically set at a higher pressure level than pressure relief valves.

• The size of a relief val...read more

NPSH Available is the amount of fluid pressure available at the suction of a pump.

• NPSH Available is the difference between the absolute pressure at the suction of the pump and the vapor pressure of the fluid being pumped.

• It is important to ensure that the NPSH Available is greater than the NPSH Required for the pump to avoid cavitation.

• NPSH Available can be increased by increasing the pressure at the suction of the pum...read more

Cavitation in pumps can be troubleshooted by identifying the root cause and taking corrective actions.

• Check for low suction pressure or high discharge pressure

• Inspect the impeller and casing for damage or wear

• Ensure proper alignment of the pump and motor

• Verify that the pump is properly primed

• Consider changing the pump design or increasing the size of the suction pipe

• Install a cavitation eliminator or inducer

• Monitor the...read more
