Question

In the Tyler standard screen series, with the inclusion of intermediate screens the ratio of the mesh dimension of any screen to that of the next smaller standard screen is...........

Answer 1

Tyler’s screen series is based on the ratio of 1.414, the square root of 2, as the constant in different sizes of the standardized screen scale. Taking 0.0029 in. or 0.074 mm. the opening in the 200-mesh sieve as the base or starting point, the diameter of each successive opening is exactly 1.414 times the opening in the previous sieve.
