The hydrometer sinks deeper in low-density liquids such as kerosene, gasoline, and alcohol, and less deep in high-density liquids such as brine, milk, and acids. It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom.
At the bottom of the hydrometer is a weighted bulb and at the top is a pan for small weights. To use the hydrometer, one first accurately determines its weight (W) while it is dry. Next, the device is placed in water, and a weight (w) sufficient to sink a marked point on the rod to the water-line is placed on the pan.
ocean depth feeler gauge: gap widths forward looking infrared (FLIR) detects infrared energy (heat)converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations. framing square: right angles in construction frequency counter: frequency of alternating current ...
An illustration exists of a unitless E – Y diagram and how Energy and depth of flow change throughout a Parshall Flume. The two blue lines represent the q values, q 1 for the flow before the constriction, and q 2 representing the value at the constriction (q = Q/b = ft 2 /s, or flow over width in a rectangular channel).
Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [5]
As it does every year, NORAD, the North American Aerospace Command, tracked Santa on his trip around the world on Christmas Eve so children and families could see where he was.
It’s officially spooky season, a time for candy, horror movies and of course, haunted houses. Now, you may not believe in ghosts or the supernatural, but there are plenty of people who do.
The instrument is lowered into the water in what is called the downcast to a determined depth or to a few meters above the ocean floor, generally at a rate of about 0.5 m/s. Most of the time a conducting wire cable is attached to the CTD frame connecting the CTD to an onboard computer, and allows instantaneous uploading and real time ...
