	Paddle steamer -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-10-08)
		A paddle steamer, paddleboat, or paddlewheeler is a (A vessel that carries passengers or freight) ship driven by one or more paddle wheels driven by a (External-combustion engine in which heat is used to raise steam which either turns a turbine or forces a piston to move up and down in a cylinder) steam engine.
		The first paddle steamer was the Pyroscaphe built by Marquis Claude de Jouffroy of (A city in east-central France on the Rhone River; a principal producer of silk and rayon) Lyons in (A republic in western Europe; the largest country wholly in Europe) France, built in 1783.
		In oceangoing service, the paddle steamer became obsolete rather quickly with the invention of the screw (A mechanical device that rotates to push against air or water) propeller, but they remained in use in coastal service, thanks to their shallow draught and good maneuverability.

	Paddle steamer - Wikipedia, the free encyclopedia
		A paddle steamer, paddleboat, or paddlewheeler is a ship or boat propelled by one or more paddle wheels driven by a steam engine.
		The first sea-going trip of a paddle steamer was that of the Albany in 1808, which steamed from the Hudson River along the coast to the Delaware River.
		There are two basic ways to mount paddle wheels on a ship; a single wheel on the rear, known as a stern-wheeler, and a paddle wheel on each side, known as a side-wheeler.

		Forward paddle wheel 62 and aft paddle wheel 66 are pivotably mounted to and extend laterally away from the port side of the fuselage 60, and forward paddle wheel 64 and aft paddle wheel 68 are pivotably mounted to and extend laterally away from the starboard side of the fuselage 60.
		Aft paddle wheels 66, 68 are mounted to the fuselage 70 for rotation about a second common axis generally parallel to the first common axis and laterally spaced from the first common axis between the first common axis and the tail of fuselage 70.
		Pitch control is achieved by differentially adjusting the strokes of the actuators and the pivot angle of the blades of the forward paddle wheels 62, 64 relative to the strokes of the actuators and the pivot angles of the blades of the aft paddle wheels 66, 68.

		The paddles of the wheel may be constructed to minimise resistance to the flow of oncoming water above the transverse axis of the wheel.
		A rotary member 9, for example in the form of a paddle wheel, is mounted in the region of the downstream end of the base 1 and is provided for extracting energy from the water flow.
		The arrangement is such that the paddle blades are urged against the central core when generating power to cause the paddle wheel to rotate, but when not generating power are free to rotate and present minimal resistance to the flowing water.

		The verb seems to be a frequentative form of " pad," to walk, cognate with " path," or of "pat," to strike gently, an onomatopoeic word; it may have been influenced by the Fr.
		The verb may have given rise to "paddle," an oar, an easy transition in sense; but the New English Dictionary identifies this with the word for a small spade, which occurs earlier than the verb, and seems to have no connection in sense with it.

	Paddle wheel (Site not responding. Last check: 2007-10-08)
		The paddle wheel is a large wheel, generally built of a steel framework, upon the outer edge of which are fitted numerouspaddle blades (called floats).
		In oceangoing service, the paddle steamer became obsolete rather quickly with the invention of the screw propeller, but they remained in use in coastal service, thanks to their shallow draughtand good maneuverability.
		Some paddle steamers still operate on the MississippiRiver, as do a couple in the United Kingdom; the coastal paddle steamer PS Waverley, built for service in the Firth of Clyde, is the last seagoing paddle steamer in operationanywhere in the world.

	Pond Aeration
		The maximum rotational speed of a tractor-powered paddle wheel aerator for extended operation is limited by the tractor, its recommended power takeoff speed under load, and the gear reduction of the paddle wheel.
		Electric paddle wheel units are 4 to 12 feet long with paddles of triangular cross section and a total drum diameter of about 28 to 36 inches.
		Paddle wheel speed is usually 80 to 90 rpm with a paddle depth of about 4 inches, enough to load the motor.

	Paddle Wheel Technology from Cancoppas Limited
		These flow meters consist of a paddle wheel located in the flow path of the flow meter.
		As fluid flow causes the paddle wheel to rotate, an electrical (AC) voltage is generated in a magnetic pick up coil, mounted on the meter housing (body), located immediately adjacent to the flow path.
		As each paddle wheel passes through the magnetic field, a pulse is generated.

		The problem with radial (conventional) paddle wheels is not so much that the blades aren't vertical but as Bob identifies, the blade speed changes.
		The blade on a radial paddle wheels changes its speed between when the blade enters and exits - slowest - and the mid stroke position where the blade travels the fastest.
		This arrangement also put the wheel in the lee of the main house, and the working part of the blades in the favorable current created by the flat-bottom hull ahead.

	Flow Measurement Laboratory
		If the paddle wheel sensor were a positive displacement measurement device, the volume of fluid going through the device would always produce a certain rotation of the shaft.
		However, for the paddle wheel sensor, variables such as the portion of the flow hitting the wheel, drag on the wheel, the alignment of the flow velocity vector relative to the surfaces of the vanes, etc. affect the relationship between flow rate and rotation velocity.
		We have used a paddle wheel transducer, a mass-flow controller, and a rotameter to measure the flow rate in an enclosed pipe.
