"WebbBecause a poise is already 1/10 of a pascal second. Remember one poise is 1/10. And so a centipoise is really a millipascal second or water at 20 degrees Celsius is 1.0 millipascal seconds or centipoise. Now you can see there's a huge dependency on temperature. The viscosity is highly dependent on temperature. " - Pipe flow velocity
