Question 34
MTMCQ2 marksNeeds review
For a fully developed 1-D flow of a Newtonian fluid through a horizontal pipe of radius R (see figure), the axial velocity (v_z) is given by:
where, ΔP is the pressure difference (P₁ − P₂), μ is the viscosity, r is the radial distance from the axis and L is the length of the tube. The shear stress exerted by the fluid on the tube wall is:
