The viscosity of 5W-30 motor oil changes from 6.4 N -s/m² at -30 °C to 0.0090 N -s/m² at 100 °C. Model the oil circulation system of a car engine as a tube of radius 5.0 mm and length 2.1 m, driven by a pump that produces a pressure difference of 110 kPa across the ends of the tube. (a) What volume flow rate does the pump produce when the oil is at -30 °C?
