...Determination of Constants. Let us take the equation of a straight line, y = ax+b. By definition -j- **is the tangent of the angle which the line makes with the** z-axis. This is equal to a and determines this constant. When x=0, y=b. This determines the constant... | |

...The position of the line on the viscosity axis at zero flour concentration is determined by a, and b **is the tangent of the angle which the line makes with the** horizontal. Thus b is directly related to the slope of the line and may be taken as a numerical value... | |
