Finally, many commercial radiator antifreeze products have fluorescein added to enable radiator leaks to be detected using a Wood's lamp. Following ingestion of antifreeze products containing ethylene glycol and fluorescein, a Wood's lamp may reveal fluorescence of a person's mouth area, clothing, vomitus , or urine which can help to diagnose ...
The first engines relied on thermosiphon cooling alone, where hot coolant left the top of the engine block and passed to the radiator, where it was cooled before returning to the bottom of the engine. Circulation was powered by convection alone. Other demands include cost, weight, reliability, and durability of the cooling system itself.
Proper engine coolant and a pressurized coolant system obviate these shortcomings of water. With proper antifreeze, a wide temperature range can be tolerated by the engine coolant, such as −34 °F (−37 °C) to +265 °F (129 °C) for 50% (by volume) propylene glycol diluted with distilled water and a 15 psi pressurized coolant system.
a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine; a water pump, usually of the centrifugal type, to circulate the coolant through the system; a thermostat to control temperature by varying the amount of coolant going to the radiator;
Although men had the highest mortality rates overall, women saw the "largest proportional rise," according to the study findings, with deaths going from 4.8 per 100,000 in 1999 to 12 in 2020.
A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.
Georgian officials believe that 12 people died at a ski resort due to an apparent carbon monoxide poisoning, according to reports by the BBC, Sky News, and other news outlets.
And while food poisoning can happen anywhere, fast-food chains have seen some of the worst outbreaks due to their massive scale. Data from iwaspoisoned.com, a food safety reporting platform, shows ...
