The spill area may be scrubbed with a stiff brush and warm, soapy water. [34] The soapy water is not recommended to be drained in a storm drain. [34] Checking vehicles regularly for leaks. [33] Storing antifreeze in clearly marked original sealed containers, in areas that are inaccessible to pets [33] or small children. [34]
Water freezes at 0 °C; however, a mixture of 70% de-icing fluid and 30% water freezes below −55 °C. This is known as the eutectic concentration – the mixture proportion where the freezing point of the mixture is at its lowest point, and lower than either of the component substances.
Starting fluid is sprayed into the engine intake near the air filter, or into the carburetor bore or a spark plug hole of an engine to get added fuel to the combustion cylinder quickly. Using starting fluid to get the engine running faster avoids wear to starters and fatigue to one's arm with pull start engines, especially on rarely used machines.
This liquid is miscible with water, and at standard atmospheric pressure (101.325 kPa) has a boiling point of 286.5 °C and a freezing point of −7 °C. It is also soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in diethyl ether; and insoluble in oil, fat and most hydrocarbons.
In this application, ethylene glycol flows down from the top of a tower and meets a rising mixture of water vapor and hydrocarbon gases. Dry gas exits from the top of the tower. The glycol and water are separated, and the glycol recycled. Instead of removing water, ethylene glycol can also be used to depress the temperature at which hydrates ...
Drinking ether is challenging as it boils below body temperature and is not miscible with water, requiring precautions: . There is an art in swallowing the ether. The drinker first washes out his mouth with water “to cool it;” next he swallows a little water to cool his throat; then he tosses down the glass of ether; finally, he closes in with another draught of water to keep the ether ...
For a cleaner product, the reaction is conducted in the gas phase or in an organic solvent. Ethylene fluorohydrin is obtained differently, by boiling hydrogen fluoride with a 5–6% solution of ethylene oxide in diethyl ether. The ether normally has a water content of 1.5–2%; in absence of water, ethylene oxide polymerizes. [37]
In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.
