A glucose solution of viscosity 2.2 × 10−3 N⋅s/m2 and density 1030 kg/m3 flows from an elevated open bag into a vein. The needle into the vein has a radius of 0.20 mm and is 3.0 cm long. All other tubes leading to the needle have much larger radii, and viscous forces in them can be ignored. The pressure in the vein is 1000 N/m2 above atmospheric pressure. Determine the pressure relative to atmospheric pressure needed at the entrance of the needle to maintain a flow rate of 0.10 cm3/s. To what elevation should the bag containing the glucose be raised to maintain this pressure at the needle?

Water, with density of 1000 kg/m3 and kinematic viscosity of 1.0 x 10- m2/s, is pumped through a total length of 60 m of pipe from a lower reservoir to a higher reservoir. The inner diameter of the pipe is 30 cm. Both reservoirs are open to the atmosphere, and the water surface of the higher reservoir is 10 m above that of the lower reservoir. The entrance from the lower reservoir to the pipe is sharp-edged, and along the...
Water (density = 1000 kg/m3, viscosity = 1.15 x 10-3 N-s/m2) is delivered from a large reservoir upstream (Section"1") through two mortar lined steel circular pipes arranged in series to another large reservoir downstream (Section "2") as shown in Figure E4.7 The upstream pipe is 80 m long and 0.15 m in diameter, whereas the downstream pipe is 50 m long and 0.1 m in diameter. Both pipes have sharp-edged entrance and exit. Consider both major and minor losses. Determine...
ater (density 1000 kg/m3, viscosity 0.001 N-s/m2) flows from a large reservoir through straight pipe into the atmosphere at a flowrate of 2.5 m3/s. The reservoir is pressurized to 200 kPa (gage). The pipe has a diameter of 0.5 m and absolute roughness of 0.1 mm. The pipe also contains a turbine that has an efficiency of 0.6. si A) Is the flow in the pipe laminar or turbulent? (3 pts) B) What is the power transmitted from the turbine...
