Consider Bernoulli's equation as it applies to an incompressible fluid flowing through a horizontal pipe of varying diameter. Assume that you measure pressure and kinetic energy in the fluid along the pip in the direction of fluid flow. What happens to the sum of the pressure and energy per unit volume? a. It increases as the pipe diameter increases. b. It decreases as the pipe diameter increases. O. It remains constant as the pipe diameter increases. O d. No choices above are valid.

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
