2. In a 0.32 cm diameter pipe, motor oil passes and is released into the atmosphere with a flow rate of 0.20 ml / s. At a temperature of 20 °C, the viscosity of the oil is 30.0 x 10-3 Pa s and the density is 800 kg / m3. To measure the pressure drop, two piezometric tubes or gauges are placed 25.0 cm apart as indicated in the figure. Ah 25 cm
