Viscosity Measurement of Water and Steam at High Temperatures and High Pressures

Viscosity of water and steam was experimentally investigated in a wide range of temperatures up to 900°C and of pressures up to 1000 bar. In this investigation, a capillary viscometer was used in the closed circuit system with a high pressure injector and a mercury manometer. Measured results are compared with the standard values of the ICPS Skeleton Table (1964), and with experimental values of other investigations. A newly correlated equation represents experimental results within about 2% deviations.
