In the development of a new piece of equipment, it is necessary to measure the shear stress (7) between two parallel plates where the lower plate is stationary and the upper plate moves at a velocity (V) of 2m/sec. The plates are 0.025m apart (h). The shear stress 7 is estimated by V 2m/sec T = HT="0.025m "h = 80µ. The viscosity (µ) in N – sec/m² is a function of temperature.
