“Schedule 40” refers to pipe

“Schedule 40” refers to pipe

• A. flow capacity
• B. friction loss
• C. tubing strength
• D. wall thickness

Answer: (D)

In piping terminology, “Schedule” designates the wall thickness of the pipe. For a given nominal size, Schedule 40 specifies a particular, standard wall thickness that gives a certain strength and pressure rating. So when you see Schedule 40, you’re being told about how thick the pipe walls are, not how much fluid it can carry or how much friction the flow will experience. Flow capacity and friction loss depend mainly on the inside diameter, flow rate, and roughness, while Schedule 40 is about the pipe’s wall thickness, which also influences internal diameter slightly and the pipe’s structural strength.
