Aparticle located at a point within a fluid flow has velocity components of u = -2 m/s and v = 3 m/s, and acceleration components of ax = -1.8 m/s2and ay = -2 m/s2.

determine the magnitude of the streamline component of acceleration of the particle.

determine the magnitude of the normal component of acceleration of the particle.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
