Question
I require these 5 questions answered. I want diagrams and step-by-step detailed solutions please!
2.1 compute the Reynolds number for 258C water flow in a 1-in nominal diameter sanitary pipe at 0.5 kg/s. What are the flow characteristics?
2.2 Sulphuric acid with a density of 1980 kg/m3 and a viscosity of 26.7 cP is flowing in a 35-mm-diameter pipe. If the acid flow rate is 1 m3/min, what is the pressure loss due to friction for a 30-m length of smooth pipe?
2.3 estimate the mean and maximum velocities for a liquid with a flow rate of 20 L/min in a 1.5-in nominal diameter sanitary pipeline. The liquid has a density of 1030 kg/m3 and viscosity of 50 cP. Is the flow laminar or turbulent?
2.4 compute the viscosity of a fluid that would allow a pressure drop of 35 kPa over a 5-m length of 0.75-in stainless steel sanitary pipe if the fluid is flowing at 0.12 m3/h and has a density of 1010 kg/m3. Suppose laminar flow. The diameter of the tube is 0.62 inches.
2.5 A 2-cm-diameter, 5-cm-long capillary-tube viscometer is being used to measure viscosity of a 10 Pa s liquid food. Determine the pressure required for measurement while a flow rate of 1 kg/min is desired and ρ51000 kg/m3.
