Chemical Engineering 374 Fall 2011 Reading Questions 22—Chapter 14.1-14.2 (not 783-789) Name ________________________________________________________ 1. What is the definitional difference between a pump and a turbine? By what criteria is a pump further defined into a fan, a blower, and a compressor? 2. Why is the brake horsepower of a pump always greater than the power actually delivered to the fluid? 3. At what point on the pump performance curve would we ideally like to have a pump operate? 4. In Example 14-1, if the minor losses could be neglected, in which direction would the

For two pumps in series, how was the curve for three pumps (blue line) obtained in Figure 14-23? 7. For two pumps in parallel, how was the curve for three pumps (blue line) obtained in Figure 14-24? 8. Why is an overpressure protection system needed for positive-displacement pumps? 9. When are multistage axial-flow pumps used (i.e., to provide what type of performance?...
