Webcurve for a given fluid, valid for all flow rates, tube lengths and tube radii. The Rabinowitch Correction calculates the real wall shear rate from the apparent wall shear rate using such a plot. γ˙ w = 3+b 4 γ˙ A (8-20a) b ≡ d(log ˙γ A) d(logσ w) (8-20b) For a derivation of this, … WebHere again, the flow curve diagram on a linear scale shows that the model function is shaped as a curve with an intercept on the shear stress axis (comparable with curve 2 in Figure 1 left). The parameter p is used to …

WebICAR Rheometer 73 recommended. During each step the speed is held constant and the average speed and torque are recorded. The plot of torque versus speed of vane rotation is the flow curve. The ICAR Rheometer software performs all the necessary functions: operates the driver, records the torque, computes test results, and stores data. WebRheometers are able to determine many more rheological parameters.
