ABSTRACT
New measurements have been made for the viscosity of cyclopentane between 258 K and 298 K at pressures up to approximately 380 MPa with a self-centering falling-body viscometer. These extend earlier high-pressure measurements made below 25 MPa by Assael and Dalaouti. A correlation function is used to represent the results as a function of temperature and molar volume with a standard deviation of ?0.3%. The uncertainty in the measurements is estimated at ?1%.
