 SV It is important to control the gap between the spindle

SV It is important to control the gap between the spindle and the cup. The viscometer cone rotates at a set rate and the device measures the torque required to do so. Based on the cone geometry, the torque is converted to shear stress and viscosity is calculated using the formula, t. ui If the gap is not set correctly, which term will be incorrect? If the gap is too large, will the viscosity calculated be overestimated, underestimated, or unaffected? yx
