 FLUID MECHANICS - CASE STUDY SOLUTION Problem Description Velocity Distribution Acceleration Distribution For the center streamline, the velocity of the fluid is one-dimensional and linear:      u = ax + b where a and b are constants. Based on the experimental measurements, u is 10 m/s when x is zero (inlet) while u is 50 m/s when x is 0.5 m (outlet). Hence, it can be determined that the constants a and b are 80 and 10, respectively. The velocity distribution is thus given by      u = (80x + 10) m/s The acceleration of the fluid is given by (use the fact that v = w = 0 for 1-D flow):       The local accelerations of the fluid at the inlet and outlet are then determined to be 800 m/s2 and 4,000 m/s2, respectively.
