Question: Using the equations for final velocity in terms of masses and initial velocity for a perfectly inelastic collision, work out the final kinetic energy. Calculate the initial kinetic energy and show that kinetic energy is not conserved. Use variables, no numbers. The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
A fluid flows axially between two concentric circular cylinders. The inner cylinder has a radius of "a" and the outer radius is "b". For fully developed flow determine: The relation between the flow rate and the pressure gradient
