Blood flows through a tube with a radius of 25 μm and a length of 1,000 μm. the pressure drop across the tube is 30 mmhg. the hematocrit in large vessels (feed hematocrit or discharge hematocrit hd) is 45%. plasma viscosity is 1.03 cp. assume that blood in the tube can be modeled as two immiscible layers: a plasma layer near the wall of thickness 4 um and a blood core region of radius 21 jm
a) use conservation of mass (mass shell balance) to prove that velocity of blood is independent in z direction (vz is not a function of z)
b)use conservation of momentum (r-momentum shell balance) to find the shear stress and velocity distributions in the plasma region and in the blood region. note: make sure to specify the boundary conditions necessary to find the four unknown coefficients that arise in the plasma and core velocity equation: s

Several processes form metal ore. match each process to its description. volcanic activity weathering hydrothermal energy rocks break down as they interact with air and water. arrowright density differences and other factors cause metals to concentrate in igneous rocks. arrowright seawater heats up from contact with hot rock, and metals dissolve in it. the water rises and contacts cooler water, causing metal ores to settle on the ocean floor. arrowright
