The dimensions of a soil sampler are given in the table

Parameter	Cutting edge	Sampling tube
Inside diameter (mm)	80	86
Outside diameter (mm)	100	90

For this sampler, the outside clearance ratio (in percent, round off to 2 decimal places) is ________

Solution:

Given:

{D}_{4}=90 {mm}

{D}_{2}=100 {mm}

Outside clearance

=\;{D_{2}-D_{4}}/{D_{4}} × 100

=\;{100-90}/{90} × 100=11.11 \%
