Chapter 8.3, Problem 5CC
A 75-gram [g] cylindrical rod is measured to be 10 centimeters [cm] long and 2.5 centimeters [cm] in diameter. What is the specific gravity of the material? Recall that the volume of a cylinder can be determined by: V= πr2 H, where r is the radius and H is the height.

s) The overall size of the system (i.e. the shell) is 5.8 inch ID and a 27-inch long tube section. Assuming
tubes are 1/2 inch in diameter (ignore thickness) and that the tubes are spaced with 1/4 inch between them. Estimate
the number of tubes that will fit in the shell.

Regardless of your answer to part 1.1, use 36 as the number of tubes and estimate the total heat transfer
You have 4 springs, one each 3.5, 6, 8.5, 11 newtons per meter.
How close an equivalent stiffness to the average of the four springs (7.25 newtons per meter [N/m]) can you make using only these springs? You may use all four springs to do this, but you may use less if that will yield an equivalent stiffness closer to the average.
