Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic.
Water can be obtained by enclosing a leafy tree branch in clear plastic, [5] capturing water vapour released by the tree. [6] The plastic allows photosynthesis to continue. In a 2009 study, variations to the angle of plastic and increasing the internal temperature versus the outside temperature improved output volumes.
In Kuwait a MSF facility uses parabolic trough collectors to provide solar thermal energy to produce 100 m 3 of fresh water a day. [8] And in Northern China an experimental, automatic, unmanned operation uses 80 m 2 of vacuum tube solar collectors coupled with a 1 kW wind turbine (to drive several small pumps) to produce 0.8 m 3 /day.
A water trough (British terminology), or track pan (American terminology), is a device to enable a steam locomotive to replenish its water supply while in motion. It consists of a long trough filled with water, lying between the rails.
Gutters prevent water ingress into the fabric of the building by channelling the rainwater away from the exterior of the walls and their foundations. [9] Water running down the walls causes dampness in the affected rooms and provides a favourable environment for growth of mould, and wet rot in timber. [citation needed] A rain gutter may be a:
A trench drain (also known as a channel drain, line drain, slot drain, linear drain, or strip drain) is a specific type of floor drain featuring a trough- or channel-shaped body. It is designed for the rapid evacuation of surface water or for the containment of utility lines or chemical spills.
An abreuvoir is a watering trough, fountain, or other installed basin: originally intended to provide humans and/or animals at a rural or urban watering place with fresh drinking water. They were often located at springs. In pre–automobile era cities, they were built as equestrian water troughs for horses providing transportation.
As the water is siphoned from the trough, water is also sucked from the timing box and the water level inside the box falls rapidly, with air drawn into the timing box through a 'snorkel' vent pipe. When the timing box has been emptied of water, air flows through the timing box and into the siphon to break the siphonic action, stopping the ...
