WebbIt is given by the formula, Ct = a (Tm – To)L----------- (2) in which Ct = the correction for temperature, in m. a = the coefficient of thermal expansion. Tm = the mean temperature during measurement. To = the temperature at which the tape is standardized. L = the measure length in m. WebbWhen the temperature of the tape differs from this standard temperature then the tape is susceptible to dimensional change. When the tape is too hot, it expands and when it is too cold it contracts. Thus, the distance measured will not be correct. The temperature correction is defined, for metric tapes, as Ct αl t tS
Tape Corrections – Civil Engineering X
is the standard temperature, when the tape is at the correct length, often 20 °C; The correction C t {\displaystyle C_{t}} is added to L {\displaystyle L} to obtain the corrected distance: d = L + C t {\displaystyle d=L+C_{t}} Visa mer In surveying, tape correction(s) refer(s) to correcting measurements for the effect of slope angle, expansion or contraction due to temperature, and the tape's sag, which varies with the applied tension. Not correcting for these … Visa mer • Local attraction Visa mer A tape not supported along its length will sag and form a catenary between end supports. According to the section of tension correction … Visa mer Manufacturers of measuring tapes do not usually guarantee the exact length of tapes, and standardization is a process where a standard temperature and tension are determined at which the tape is the exact length. The nominal length of tapes can be affected by … Visa mer WebbCombining a statement of volume with a statement of the reference temperature yields the following measurement systems. In Eastern Bloc, Brazil m3 at 20 o C; In Western Europe m3 at 15 o C; In the USA US Bbl at 60 o F. It is customary to refer to volumes at the reference temperature as Standard Volumes e.g US barrels @ 60 o F or cubic meters ... fulton township rock co wi
