Power Control Engineers Engineering Intern Interview Questions and Answers

Tube OD selection depends on factors such as fluid flow rate, pressure, and material compatibility.

• Consider fluid flow rate and pressure to determine appropriate tube OD

• Ensure compatibility of tube material with fluid being transported

• Consult industry standards and guidelines for recommended tube OD sizes

• Factor in any space constraints or installation requirements

• Perform testing and analysis to verify tube OD selection

Pump selection depends on the fluid properties, flow rate, head, and system requirements.

• Determine the fluid properties such as viscosity, density, and corrosiveness.

• Calculate the required flow rate and head based on the system requirements.

• Consider the pump type such as centrifugal, positive displacement, or axial flow.

• Choose the appropriate pump size and material based on the fluid properties and system requirements.

Design parameters for heat exchangers include heat transfer rate, pressure drop, material selection, and flow arrangement.

• Heat transfer rate: determines the efficiency of the heat exchanger

• Pressure drop: affects the flow rate and energy consumption

• Material selection: depends on the fluid properties and operating conditions

• Flow arrangement: affects the heat transfer rate and pressure drop
