a. Please select a diameter with in the observed range of 0.6 to 6 mm and calculate the falling velocity when a sodium droplet freely falls in air. The droplet ignition occurs at about 0.5 seconds after the droplet injection. b. Develop a graph of the falling velocity vs time, and Re Vs time. c. Write a discussion on using the drag coefficient for a solid sphere under isothermal condition. Use equations or other information from the handouts used to construct the following table and the plots Time (s) Falling Velocity Re Ca (m/s) 0 0.1 0.2 0.4 0.5 0.6 0.7 0.8 0.9 1 1.1 a.
