just part g |Umaxu = u(r)Is this flowa. Internal or external?b. viscous or inviscid?C. one dimensional or two dimensional?d. Find the correct expression for the velocity field u(r)e. Find the shear stress at each point in the fluid (What coordinate system should you use?)Find numbers for umax and the diameter of the pipe and the viscosity of the fluid for an application that is ofinterest to you, e.g. for blood vessels or flow in hydraulic pipes and use them for the calculations.f. Find the shear force per unit length of the pipe.g. How much does this shear force decelerate the fluid? Comment on why you think the result makes sense.

Choose correct answer: When the cylinder is cushioned at the end of the stroke, how does cushioning affect the piston's force? At the beginning of the stroke, cushioning increases the piston's force. At the beginning of the stroke, cushioning reduces the piston's force. At the end of the stroke, cushioning increases the piston's force. At the end of the stroke, cushioning reduces the piston's force.
A motor is driving an output shaft through a single-stage gears, as shown.
