Waterless urinals can save between 15,000 and 45,000 US gallons (57,000 and 170,000 L) of water per urinal per year, depending on the amount of water used in the water-flushed urinal for comparison purposes, and the number of uses per day. For example, these numbers assume that the urinal would be used between 40 and 120 times per business day. [4]
The World Health Organization recommends that pits be built a reasonable distance from the house, ideally balancing easy access against smell. [4] The distance from water wells and surface water should be at least 10 m (30 ft) to decrease the risk of groundwater pollution . [ 11 ]
While female urinals exist, they are more difficult to use, and the common practice for females is to use a bedpan. [3] Female urinals require a wider opening and must be placed between the legs. [4] For many women, female urinals are more practical in a wheelchair rather than in a bed. [5]
The pee curl (Dutch: plaskrul) is a public urinal, many of which are found in the centre of Amsterdam. They originated at the end of the 19th century, and were first installed by the Public Works Department of Amsterdam. The curl is made of a spiral-shaped steel sheet suspended half a metre above the ground by four iron legs, and painted dark ...
A urinal takes less space, is simpler, and consumes less water per flush (or even no water at all) than a flush toilet. Urinal setups can have individual urinals (with or without privacy partitions) or a communal urinal (also called a trough urinal) which is used by multiple men.
The angstrom (symbol Å) is a unit of distance used in chemistry and atomic physics equal to 100 pm. The micron (μ) is a unit of distance equal to one micrometre (1 μm). The basic module (M) is a unit of distance equal to one hundred millimetres (100 mm). The myriametre (mym) is a unit of distance equal to ten kilometres (10 km).
18.44 meters – distance between the front of the pitcher's rubber and the rear point of home plate on a baseball field (60 feet, 6 inches) [127] 20 meters – length of cricket pitch (22 yards) [128] 27.43 meters – distance between bases on a baseball field (90 feet) 28 meters – length of a standard FIBA basketball court
The siriometer is an obsolete astronomical measure equal to one million astronomical units, i.e., one million times the average distance between the Sun and Earth. [13] This distance is equal to about 15.8 light-years, 149.6 Pm, or 4.8 parsecs, and is about twice the distance from Earth to the star Sirius. [14]
