WebThe following data is required for the shear rate calculation: A rheometer records the shear force via the torque at each measuring point. The torque is either preset or, if the rotational speed is the preset value, it is … WebThe unit for shear rate is 1/s = 1 s -1, also called reciprocal seconds. A rheometer records the velocity as the rotational speed at each measuring point. The size of the shear gap is also known for the measuring system …
WebAug 13, 2002 · The shear rate will have its higher values in the neighborhood of the spindle, and lower values farther away from it. That is why an open cup and spindle rehometer, like most Brookfield can only provide relative measurements, rather than exact values. If you are interested in a more detailed discussion let me know.
