A surfactant (surface active agent), such as hand-dishwashing liquid detergent, can be added to the water to significantly lower the surface tension of the water. This liquid solution will flow more easily and more rapidly in the tube than plain water, so operation of the device will be more precise, repeatable, and responsive – particularly ...
A pedestal sump pump with a float switch. A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.
Conductive level sensors are ideal for the point level detection of a wide range of conductive liquids such as water, and is especially well suited for highly corrosive liquids such as caustic soda, hydrochloric acid, nitric acid, ferric chloride, and similar liquids. For those conductive liquids that are corrosive, the sensor's electrodes need ...
21st-century hunting compound crossbow. A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun. Crossbows shoot arrow-like projectiles called bolts or quarrels.
Water gauge on a steam locomotive. Here the water is at the “top nut”, the maximum working level. Note the patterned backplate to help reading and toughened glass shroud. A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
Dry running protection, also known as dry-run protection or dry-running protection, is a type of protection mechanism to prevent a rotor, pump or stirrer shaft from operating without any medium added, as the bearing and shaft seal might be damaged if the motor is run while dry. [1]
Upon introducing surfactants (or any surface active materials) into a system, they will initially partition into the interface, reducing the system free energy by: [citation needed] lowering the energy of the interface (calculated as area times surface tension), and; removing the hydrophobic parts of the surfactant from contact with water.
Triton X-100 (C 14 H 22 O(C 2 H 4 O) n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group.
