Question

if you wanted to fill a bucket which of the following fixtures with faucets fully opened would fill it the most quickly? (assume that pipe length and size and pressure are equal to all of these.)
a bathroom basin
a kitchen sink
an outdoor hose bibb
a bathtub fill spout
a shower nozzle

question 32
the coefficient of thermal expansion is highest on
polyethylene
copper piping
polybutylene
cast iron piping
cpvc

Explanation:

Question 1

Outdoor hose bibbs are typically designed to deliver a high - volume of water quickly for tasks like filling large containers. They usually have larger openings and higher flow rates compared to bathroom basins, kitchen sinks, bathtub fill spouts, and shower nozzles under the same pressure and pipe condition assumptions.

Among the given materials, polyethylene has a relatively high coefficient of thermal expansion. Polymers like polyethylene expand more with temperature changes compared to metals such as copper and cast iron, and other plastics like polybutylene and CPVC.

Answer:

C. an outdoor hose bibb
