A 3d block with the dimensions of 50cm by 30cm by 20cm and a weight of 450 N, is going to be moved at a constant velocity of 0.8 m/s on an incline. The incline has a friction coefficient of 0.27. If a 0.45 mm thick oil film with a dynamic velocity of 0.012 Pa∙s is applied between the block and the inclined surface, what is the percent reduction in the required force?

A sphere and a circular cylinder (with its axis perpendicular to the flow) are mounted in the same freestream. A pressure tap exists at the top of the sphere, and this is connected via a tube to one side of a manometer. The other side of the manometer is connected to a pressure tap on the surface of the cylinder. This tap is located on the cylindrical surface such that the deflection of the fluid in the manometer indicates that the pressure coefficient over the cylinder is 20% greater than that for the sphere. Calculate the location of this tap. (Round the final answer to two decimal places.) The pressure tap on the cylinder must be located at an angular position .............. above or below the stagnation point.
A small blood vessel near the skin surface has a radius of 10 µm, a length of 1 µm and the pressure drop along the blood vessel is 2.50 Pa. The viscosity of blood is 0.0027 Pa.s. What is the volume flow rate of blood through this blood vessel? What is the velocity of blood flow? Vasodilation causes the radius of this blood vessel to increase to 12 µm, while leaving the pressure drop along the vessel unchanged? What is the volume flow rate through this blood vessel now? What is the velocity of blood flow?
