An aircraft lavatory or plane toilet is a small unisex room on an aircraft with a toilet and sink. They are commonplace on passenger flights except some short-haul flights. Aircraft toilets were historically chemical toilets , but many now use a vacuum flush system instead.
The 787's internal cabin pressure is the equivalent of 6,000 ft (1,829 m) altitude resulting in a higher pressure than for the 8,000 ft (2,438 m) altitude of older conventional aircraft; [62] according to a joint study performed by Boeing and Oklahoma State University, such a level significantly improves comfort levels.
The fill valve, found in the toilet water tank, can also cause problems. If you adjust this too low, it can lead to weak flushing capability. Sometimes the fill valve can also become clogged with ...
At the extremely low pressures encountered at altitudes above about 63,000 feet (19,000 m), the boiling point of water becomes less than normal body temperature. [73] This measure of altitude is known as the Armstrong limit , which is the practical limit to survivable altitude without pressurization.
A low-flush toilet (or low-flow toilet or high-efficiency toilet) is a flush toilet that uses significantly less water than traditional high-flow toilets. Before the early 1990s in the United States, standard flush toilets typically required at least 3.5 gallons (13.2 litres) per flush and they used float valves that often leaked, increasing their total water use.
Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.

The pressure-sensitive plugs are calibrated to hold water up to a certain pressure level which is higher than normal ground water pressure. Once the pore water pressure is increased to higher than that level due to an earthquake, the plugs will be released into the manhole and the water from the surrounding soils can be drained into the manhole ...
