Consider a bioreactor in which we are cultivating a production cell line at 37 C in a proprietary media blend with unique fluidic properties. The tank is fitted with a Rushton impeller (6 cm) spinning slowly enough (5 Hz) such that Re = 10 and Np = 8. If the viscosity of the cell culture fluid is 0.696 (mPa*s), calculate the shaft power, in Watts, applied to turn the impeller. Input your answer in decimal form.
