(8) He added: ├ö├ç├┐If everything goes ahead as planned, we will dredge, maintain and deepen the harbour.├ö├ç├û (9) I don't understand why you had to dredge up this story (10) The dredge returned from 1,600 meters under the sea filled with live mussels and fresh sulfide minerals. (7) He said a dredge is being used to bring up wreckage submerged under 11m of water. (6) The soundings indicated a modest depth of only 525 fathoms and there was no expectation of anything out of the ordinary when the dredge was sent down at 10 o'clock that morning. (4) dredge the bananas with sugar and cinnamon (5) Cut chicken into 1/2 inch pieces and dredge in all-purpose flour. (3) Do not dredge the pasta in flour to prevent sticking, as the flour turns to glue when cooked and, ironically, causes the pasta to stick together (using semolina flour from Italian delis instead will help). (2) At 4 A.M., they deployed the dredge in the hope of getting something before the weather got too bad but had to pull it up before it passed 1,300 fathoms. Airlift pumps are governed by the physics of Two-phase flow.(1) Brush the pie with milk and dredge with caster sugar. In such cases the pipes can be 30, 60 or more meters deep underground. Īirlift pumps are used by water utilities, farmers and others to extract water from deep wells. It is often designed to be hand-operated by a diver. Ejected debris can be either cast off (as in simplely removing overburden) or collected in a mesh cage for inspection (as more often is the case in nautical archaeology). The bubble moves water through the pipe sucking debris from the lower end and depositing it from the upper end of the pipe. Compressed air is injected into the pipe in one to three second bursts with an interval long enough to let the resulting bubble to rise to the higher, output end of the pipe. A controllable compressed air supply vents into the inside, lower end of the pipe (The input end always being the lower end). Typically, the air lift is constructed from a 3 metre to 10 metre long, 10 cm diameter pipe. A water dredge or water eductor may be used for the same purpose. An Airlift is device based on a pipe, used in nautical archaeology to suck small objects, sand and mud from the sea bed and to transport the resulting debris upwards and away from its source.
