FAQs on Bottom Gating

What is the formula to find Bottom Gating?
The formula of Bottom Gating is expressed as Bottom Gating Pouring Time = Ratio of Area/sqrt(2*Acceleration)*2*(sqrt(Length of Cylinder)-sqrt(Length of Cylinder-Height of Capillary Rise/Fall)). Here is an example- 0.00427 = 5.24/sqrt(2*12.56)*2*(sqrt(6)-sqrt(6-0.01)).
How to calculate Bottom Gating?
With Ratio of Area (Aratio), Acceleration (ac), Length of Cylinder (l) & Height of Capillary Rise/Fall (hc) we can find Bottom Gating using the formula - Bottom Gating Pouring Time = Ratio of Area/sqrt(2*Acceleration)*2*(sqrt(Length of Cylinder)-sqrt(Length of Cylinder-Height of Capillary Rise/Fall)). This formula also uses Square Root (sqrt) function(s).
Can the Bottom Gating be negative?
No, the Bottom Gating, measured in Time cannot be negative.
Which unit is used to measure Bottom Gating?
Bottom Gating is usually measured using the Second[s] for Time. Millisecond[s], Microsecond[s], Nanosecond[s] are the few other units in which Bottom Gating can be measured.
