, Select the response that fits the following statement: Refining can do all of the following to
fiber. ✔Correct Answer-External fibrillation, internal fibrillation, cutting
The stuff box provides a constant pressure head to this value. ✔Correct Answer-Basis Weight
Valve
The basis weight valve is responsible for which of the following? ✔Correct Answer-Basis

Answer-True
A paper sheet is formed at 93 g/m^2. The average fiber properties making up the sheet are as
follows: length = 1.5 mm, width = 20 micrometers, coarseness = 155 mg/km. If an inspection
area of 0.5 mm^2 is used, what is the formation index? ✔Correct Answer-0.071
A paper sheet has a density of 620 kg/m^3 and a basis weight of 85 g/m^2. What is the
thickness of the sheet? ✔Correct Answer-0.137 mm
As the inspection area that formation is measured at increases, typically the formation index
gets worse. ✔Correct Answer-False
A switch in hardwood fiber is coming to your mill. The two fibers have essentially the same
width and length. The new fiber has a higher coarseness. Your boss state that there will be a
change in the formation. Do you think this statement is True or False? ✔Correct Answer-True
A sheet has a grammage of 45 g/m^2. The coarseness of the fiber used to make the sheet is 125
mg/km. The width of the fiber to make the sheet is 40 micrometers. What is the average
coverage of the sheet? ✔Correct Answer-14.40
A tissue sheet has a grammage of 20 g/m^2. The sheet is made of fiber with the following
average properties: length = 2.6 mm, width = 35 micrometers, and coarseness = 185 mg/km. On
average, how many fiber would you expect to find in an area of 1 mm^2 for this sheet?
✔Correct Answer-41.58
You are getting ready to make a presentation to a group of co-workers. It is important to report
your findings in an accurate manner. You measured the water absorption of 10 different
samples and got a result of 12.3 g/g for water uptake. The Sample standard deviation is 4.6 g/g.
Determine the value for the blank below at a 90 % Confidence interval.
