Question

question 16 1 pts which of the following ½ -inch -diameter pipes would have the lowest pressure and flow characteristics? a 100 -foot pipe with the discharge at the same elevation as the source a 50 -foot pipe with the outlet at the same elevation as the source a 50 -foot pipe with the outlet 20 feet above the source a 100 -foot pipe with the outlet 10 feet above the source a 100 -foot pipe with the outlet 20 feet above the source

Explanation:

Step1: Understand pressure - flow factors

Pressure and flow are affected by pipe length and elevation difference. Longer pipes and higher elevation differences of the outlet from the source reduce pressure and flow.

Step2: Analyze each option

• Option 1: 100 - foot pipe, same elevation.
• Option 2: 50 - foot pipe, same elevation.
• Option 3: 50 - foot pipe, 20 - foot elevation difference.
• Option 4: 100 - foot pipe, 10 - foot elevation difference.
• Option 5: 100 - foot pipe, 20 - foot elevation difference.

Step3: Compare

The pipe with the longest length and the highest elevation difference will have the lowest pressure and flow. The 100 - foot pipe with the outlet 20 feet above the source has both a long length and a high elevation difference.

Answer:

a 100 - foot pipe with the outlet 20 feet above the source
