Width density graph (2-D graph) The flow density graph represents spray flowing vertically downwards. The flow density graph has been drawn up on the basis of theoretically calculated values. The data should be regarded as being for informational purposes only. "B100" refers to the width that you have entered in the base width (B) field. "B50" indicates 50% of the central width "B100." Density is regarded as the flow rate per unit time sprayed in each of 10 individual cells of one side of the base (B). (The flow rate of spray that falls outside of base "B" is not included in the density calculation.) Flow density is per unit width of cells receiving water. Area density graph (3-D graph) The flow density graph represents spray flowing vertically downwards. The flow density graph has been drawn up on the basis of theoretically calculated values. The data should be regarded as being for informational purposes only. Area "A100" refers to total area that you have specified. Area "A10" indicates 10% of the central Area "A100." The density is regarded as the flow rate per unit time sprayed in each of 10 individual cells of one side of the base (B). (The flow rate of spray that falls outside of base "B" is not included in the density calculation.) For the purpose of flow density measurement, the cells receiving the sprayed water are taken to be square in section. The color shading of a 3D graph has five increments. The opacity increases for every additional 20% of flow density.
