### (a) Sketch of a 'Shell and Tube' Cooler and Parts Description
A simple line sketch would show a cylindrical outer shell with inlet and outlet connections for one fluid, and end covers (water boxes) at both ends. Inside the shell is a bundle of tubes held between two tube plates. The end covers have partitions to direct the flow of the second fluid through the tubes in one or more 'passes'.
**Key Labeled Parts:**
1. **Shell:** The outer casing of the cooler, which contains the tube bundle and the shell-side fluid.
