Around 1/8th of a turn on the threaded rods which set the roll gap is required for this. The thickness of the annealed brass sample is measured using the calipers. The four inch long sample is placed in the roll gap. The roller is then switched on so rolls pick up the sample and roll it, with the samples coming out of the opposite side of the ...The company's chemist puts this information in the percent yield formula in the appropriate places. (23.7 / 54.3) X 100 = Percent Yield. The chemist divides 23.7 by 54.3 to arrive at the unrefined percent yield value of 0.436. He multiples this decimal value by 100 to get the actual percent yield. 0.436 X 100 = 43.6.
