Scene 20 (35m 29s)

Fluid is to be injected into a blood vessel at a rate of 10 -5 m 3 .min -1 through a tube of 0.5 mm in internal diameter. The fluid is in a container of large cross-sectional area, open to the atmosphere. How high above the end of the tube must the free surface of the fluid be? The gauge pressure in the blood is 100 mm Hg. Ignore the viscosity of the fluid, which has a density of 10 3 kg.m -3 ..
