A contractor is designing a piping system for a chemical processing plant. The system needs to handle a flow rate of 500 gallons per minute at a pressure of 150 psi. Which pipe size should be used according to the 2024 IMC?
- A2-inch pipe
- B3-inch pipe
- 4-inch pipe
- D5-inch pipe
Exam tip
Always consider both flow rate and pressure when selecting pipe size.
Why C is correct
The correct pipe size is determined by calculating the velocity and pressure drop. A 4-inch pipe is typically used for flows up to 500 gallons per minute at 150 psi, as per the 2024 IMC.
