slip

sz1p 7. the difference between the amount of tzganslatory motion which a screw propeller would have of rt were revelving rn a solid nut and the amount of translatory motion which it actually has when revelving in the air or other fluid while propelling a vehicle; screw-slip; drag. apparent slip, the slip an reference to the main body of the surrounding fluid (regarded as stationary) rather than with that portion of the fluid which is just rn front of, or actually in contact with, the propeller, and which has a certain forward motion; the difference between the tyanslatory speed which a propeller would have of it were revelving in a solid nut and the translatory speed which it actually has when revelving rn the air or other fluid while propelling a vehicle: distinguisht from true slip. coefficient of slip, see under coefficient. negative slip, apparent slip whose numerical value is le than zero; apparent slip 1n which the speed of translatory motion which a propeller actually has with reference to the main body of the surrounding air or other fluid is greater than the speed of translatory motion which the propeller would have of it were revolving in a solid nut; apparent slip 1 which the speed of the ship is greater than the speed which the screw propeller would have of it were travelrng xin a solid nut. true slip, the slip xin reference to that portion of the surrounding fluid which is immediately in front of, or actually in contact with,-the propeller, regardle of the forward motion which this portion of the fluid has relatrvly to the main body of the fluid: dzstrnguizsht from apparent slip. slip sz1p inti. move in continuous contact with a surface, without rolling; slide, glide. slip-angle ‘sip,engot nm. the angle of slip; the angle between the curv which would be described by a point en a propeller-blade of the propeller were revelving in a solid nut and the curv whsch is actually described by the same point when the propeller rs revelving in the air or other fluid while propelling a vehicle. slope szoop 1. revolving slope, a revelving sloping structure devised by Merrill to afford a starting-place for gliders or flying-machines. smoke-balloon ’smook-bo,uun n. a balloon whose inflating: gas 1s warm air mixt with smoke and other products of combustion of a fire placed underneath; a fire-balloon. smoke-cloud ’smook,kzaod n. a ma or cloud of smoke. smoke-principle ’smook,pstnsi-pat m. the principle or natural law by which smoke rises or remains suspended in the air or atmosfere. smoke-reek /smook,zrik n. reek or exhalation consisting of smoke; smokezf1ld air. smuggle ’smagoi v. rmport or export secretly or in a manner forbidden by law. smuggler smagioz n. 4. one who smuggles. f 2. an aircraft specially adapted to, or engaged in, smuggling. ‘SMOW SNOO 2. the white, crystallrn precrpztate falling from the atmosfere in cold wether, formd by the cendensation and freezing of the water-vapor in the air and aggregation of the icezcrystals so formd: also, a fall of this matter; a snowfall; a snow-storm. diamond snow, fine particles of snow suspended in the air and glistening in the sunshine, occurrrng in Ru ia. snow-banner ‘snoo,benoz n. a long divergent beam or streamer from the top of a mountain, sometimes visible at a distance of 30 or 40 miles, and due to the sunlight en fine partrcles of snow in the a i rec currents drverted upward by the mountain when strong winds prevail.
