1. A capillary tube is being used to measure the viscosity of a Newtonian liquid. The tube has a 4-cm diameter and a length of 20 cm. Estimate the viscosity coefficient for the liquid if a pressure of 2.5 kPa is required to maintain a flow rate of 1 kg/s. The liquid density is 998 kg/m3 2. Calculate the viscosity of a fluid that would allow a pressure drop of 35 kPa over a 5 – m length of 3.4 in. stainless steel sanitary pipe if the fluid is flowing at 0.12 m3/hr and has a density of 1010 kg/m3. Assume laminar flow. 3. At 2 cm diameter, 5 cm long capillary-tube viscometer is being used to measure viscosity of 10 – Pa.s liquid food. Determine the pressure required for measurement when a flow rate of 1 kg/min is desired and ρ= 1000 kg/m3.
