what is the viscosity of human blood?
In pascal-seconds (Pa·s), the viscosity of blood at 37 °C is normally 3 × 10−3 to 4 × 10−3, respectively 3 - 4 centipoise (cP) in the centimetre gram second system of units. Blood viscosity can be measured by viscometers capable of measurements at various shear rates, such as a rotational viscometer.
