Answer to Question 1

Centrifugal compressors are able to pump large volumes of refrigerant as compared to reciprocating compressors. However they do not develop the high side discharge pressures of a reciprocating compressor. Since low pressure refrigerants do not require such high discharge pressures, they are ideally suited for centrifugal chiller applications.

Answer to Question 2

A single stage centrifugal compressor only has one impeller while a two stage unit would have two impellers. Multiple stage units develop higher pressures as compared to single stage units.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
