Question

which factor is important for determining the pipe size and layout in a plumbing system design?

a maintenance accessibility
b type of insulation
c water demand
d building materials

Explanation:

Analyze the design requirements

In Plumbing System Design, determining pipe size and layout depends directly on the volume of water required at each fixture.

Evaluate the options

• Maintenance Accessibility: Affects installation location, not sizing.
• Type of insulation: Affects thermal retention, not sizing.
• Water demand: Directly determines flow rate and required pipe diameter.
• Building materials: Affects structural support, not sizing.

Select the correct factor

Water demand is the primary factor for sizing pipes.

Answer:

• (A) Maintenance Accessibility
• (B) Type of insulation
• (C) Water demand (Correct answer)
• (D) Building materials
