Comment: Figure 4 does not match the graph of figure 5 the far and near dials do not match. figure 4 shows 12 inch between and figure 5 shows 5 inches. Also it would be nice if figure 4 was in the same orientation as figure 5 with the dials and feet orientation.

Comment: The graphic displayed in Figure 4 is supposed to show a Labyrinth Compressor at position A. The compressor at position A is supposed to show a crankshaft, with a connecting rod attached to the crosshead. However, the graphic shown displays what appears to be an upside down single acting piston floating above some oil. The graphic should be updated to correctly show a crankshaft and connecting rod

Comment: Figure 20 is not a picture showing a rigid hone. It is a flexible hone. Here is a link to a rigid hone. The original figure 20 image could be used in the section discussing the flexible hone. https://www.lislecorp.com/specialty-tools/engine-cylinder-hone

Comment: Self-test question #23 on page 75 does not specify which type of Shell and Tube heat exchanger and the answer contradicts some of the information earlier in the module. Page 33 top paragraph states that dirty fluid should be routed through the shell and clean fluid through the tubes for a U-tube shell and tube exchanger Page 36 first bullet point states that in a "double tube sheet" shell and tube exchanger the dirty fluid should flow through the tubes and clean fluid through the shell. Therefore, to prevent confusion for the students, The self-test question on page 75 needs to specify the type of exchanger. It could be re-worded to state; U-tube exchangers should have dirty fluids routed on the SHELL side since the bundle can be removed for cleaning. The TUBE side is restricted to clean fluids. Thank you

Comment: Nether the paragraph or figure 4 mention the direction of rotation. It would make it easier for a student to understand the operation of the vane compressor if the paragraph or diagram mentioned the rotation direction. (clockwise)

Comment: All the pictures on both pages are incorrect. Figure 29 is showing a liquid ring compressor and not vane. Picture 30 is the same as 29. It's showing the wrong compressor and wrong operation. Figure 31 is showing a seal and not a Rotor/Stator as the image stands below.
