Final answer:
The baseline flush rate of a water closet can vary depending on the age and design of the toilet. Older toilets typically have a flush rate of around 3.5 gallons per flush, while newer, more water-efficient toilets have a flush rate of 1.6 gallons per flush or less. Low-flush or dual-flush toilets are designed to use less water without sacrificing flushing power.
Step-by-step explanation:
The baseline flush rate of a water closet refers to the amount of water used in a single flush to remove waste from the toilet bowl. The baseline flush rate can vary depending on the age and design of the toilet.
Older toilets typically have a flush rate of around 3.5 gallons (13.2 liters) per flush, while newer, more water-efficient toilets have a flush rate of 1.6 gallons (6 liters) per flush or less. These low-flush or dual-flush toilets are designed to use less water without sacrificing flushing power.
For example, a modern water closet with a baseline flush rate of 1.28 gallons (4.8 liters) per flush can effectively remove waste while using less water compared to older toilets.
