2.10The flow of a liquid in a 2-in. diameter steel pipe produces a pressure drop due to frictionof 72.68 kPa. The length of pipe is 40 m and the mean velocity is 3 m/s. If the density ofthe liquid is 1000 kg/m², thena) Determine the Reynolds number.b) Determine if the flow is laminar or turbulent.c) Compute viscosity of the liquid.d) Estimate the temperature, if the liquid is water.e) Compute the mass flow rate.A single- cylinder rotational viscometer is used to measure a liquid with viscosity of 100cP using a spindle with 6-cm length and 1-cm radius. At maximum shear rate (rpm=60),the measurements approach a full-scale reading of 100. Determine the spindle dimensionsthat will allow the viscometer to measure viscosities up to 10,000 cP at maximum shear2.11.rate.2.12.Ais being used to transport a liquid food product (p = 1000 kg/m³, µ = 1.5 cP) frompumpa holding tank to a filling machine at a mass flow rate of 2 kg/s. The liquid level in theholding tank is 10 m above the pump, and the filling machine is 5 m above the pump.There is 100 m of 2-in. nominal diameter sanitary pipeline between the holding tank of thefilling machine, with one open globe valve and four medium-sweep 90° elbows in thesystem. The product is being pumped through a heat exchanger with 100 kPa of pressuredrop due to friction before filling. Determine the theoretical power requirement for thepump.
