From the graph. Experimental values of Dynamic viscosity engine oil SAE 10W-30 at room temperature without changing the rotors and Dynamic viscosity value speed average 0.054 Pa * s, which is close to the value of Dynamic viscosity used rotor No. 2 and No. 3, No.2, which should be used if another extension is used to measure the viscosity range was born to cause unexpected movement and speed that should be used is 1.5 round speed rpm.
