Fluid is being given to a patient by an IV in a vein of their arm. The fluid is a saline solution with a density of 1005 kg/m³. The fluid enters the vein through a 20-gauge needle with an inside diameter of 0.603 mm. The surface of the saline in the bag is 0.60 m above the end of the needle and the pressure at this surface is atmospheric. The gauge pressure in the patient's vein is 10 mm Hg. A. What would be the flow rate (in mL/min) of saline solution into the vein if there were no losses of mechanical energy in this process? B. Given that the actual flow rate is 5.0 mL/min, what are the frictional energy losses in J/kg? vein gauge P needle atm saline IV fluid = 10 mm Hg

Transcribed Image Text:Fluid is being given to a patient by an IV in a vein of their arm. The fluid is a saline solution with a
density of 1005 kg/m³. The fluid enters the vein through a 20-gauge needle with an inside diameter
of 0.603 mm. The surface of the saline in the bag is 0.60 m above the end of the needle and the
pressure at this surface is atmospheric. The gauge pressure in the patient's vein is 10 mm Hg.
A. What would be the flow rate (in mL/min) of saline solution into the vein if there were no losses of
mechanical energy in this process?
B. Given that the actual flow rate is 5.0 mL/min, what are the frictional energy losses in J/kg?
