Assume the line AB has a rising slope and BC a falling slope. 2. find the mV for buffer soln. = 264.879m. The basis of this relationship, if a variable is unrelated to other variables, it can be eliminated from the list. Let us find the horizontal distance by the Pythagoras theorem. ~ The required correction = 0.82 / 2 x 30 = 0.0167 m. Hence the horizontal length = 30 0.0167. The sign of the correction is plus, as the effect of the pull is to increase the length of the tape and consequently, to decrease the measured length of the line.
