Final answer:
Urinals shall be 15 diameters deep minimum measured from the outer face of the urinal rim to the back of the fixture.
Step-by-step explanation:
In engineering, the depth of urinals is specified to ensure proper functionality and user comfort. According to newer guidelines, urinals should be at least 15 diameters deep when measured from the outer face of the urinal rim to the back of the fixture.
For example, if the diameter of the urinal is 1 meter, then the minimum depth would be 15 meters. This is to provide enough space for the urine to drain properly and prevent splashing.
It is important to note that these guidelines have changed over time. Previously, a rule of thumb was to have urinals 7-8 diameters deep, but current research suggests a deeper depth for improved performance and hygiene.
Urinals should be 15 diameters deep minimum, measured from the outer face of the urinal rim to the back of the fixture. This is a more modern measurement compared to the older "rule of thumb," which suggested 5 to 8 diameters deep. The newer suggestions for urinal depth take into account user comfort and design efficiency.
