A neutrophil moves in blood stream with a speed of 0.28m/s the density of the blood is 1060 kg/m3 and the viscosity of the blood is 0.003 Pa-s. Determine whether the drag force or viscous force is dominant and calculate the resistive force acting on the neutrophil

Problem 7: Inputs: ● ● ● ● F₁ = 9 KN F₂= 2 KN 0 = 30° a = 3 m b=1m At what distance "d" must the resultant force be located in order for the two systems to be equivalent? a F₁ d F₂ R

As shown in figure, a block of mass M slides on a horizontal table on oil film of thickness h and viscosity μ. The mass m causes the movement. Derive an expression for the vis- cous force on the block when it moves at a velocity u. Also obtain an expression for the maximum speed of the block. M Oil, H U m
