How to Calculate Bottom Gating?
Bottom Gating calculator uses Bottom Gating=Ratio of Area/sqrt(2*Acceleration)*2*(sqrt(Cylinder Height)-sqrt(Cylinder Height-Height of capillary rise/fall)) to calculate the Bottom Gating, Bottom Gating, the liquid metal is filled in the mold from bottom to top, thus avoiding the splashing and oxidation associated with vertical gating. . Bottom Gating and is denoted by Tbg symbol.
How to calculate Bottom Gating using this online calculator? To use this online calculator for Bottom Gating, enter Acceleration (a), Cylinder Height (H), Height of capillary rise/fall (h) and Ratio of Area (Rat.area) and hit the calculate button. Here is how the Bottom Gating calculation can be explained with given input values -> 0.01325 = 2/sqrt(2*12)*2*(sqrt(0.1)-sqrt(0.1-0.01)).
