To measure low flow rates of air, a laminar flow meter is used. It consists of many small-diameter tubes in parallel. One design uses 4000 tubes, each with an inside diameter of 2 mm and a length of 25 cm. The pressure difference through the flow meter is 0.5 kPa, and the absolute viscosity of the air is 1.81 X 10-8 kPa-s. What is the flow rate of atmospheric air at 20°C in m3/s?
