Water flowing in a straight cylinder tube with radius of 3mm, has a maximum velocity U0=15cm/s. If the density and viscosity of the water are 1000kg/m3 and 1.0 x 10 -3 (Pa.s), and the flow is fully developed with a profile of u=U0(1-(r/a)2), calculate the Reynold’s number of the flow; calculate the mass flow rate in units of kg/s in the tube If the tube has a length of 50cm, calculate the flow resistance force of the tube wall imposed to the flow

Liquid flows at a rate of 1.5 L/min in a circular tube with a diameter of 5 mm. inside a circular tubeThe vascular endothelial cells are attached. One cell has a surface area of 500 μm2. To be attached to the inner wall of the tube. What force does one cell have to withstand? The viscosity of the liquid is 1.2 cP = 0.0012 Pass.

A horizontal smooth-walled cylindrical pipe has diameter 0.04 m. Water flows along the pipe with a flow rate of Q 2 x 10-4 m³ s-¹. = For water, take the kinematic viscosity as v = 10-6 m² s¹ and the 10³ kg m-³. density as p = (a) Calculate the Reynolds number and establish whether the flow is turbulent or not. (b) Show that λ = 0.035 is a good approximation of the Darcy friction factor for this flow. (c) Calculate the shear stress at the wall of the pipe, and hence find the magnitude of the drag force exerted by the water on a length 2 m of the pipe. L =
