According to Table 26-31 what would be the recommended support spacing for 2 1/8 inch type L copper pipe?
 
  What will be an ideal response?

Question 2

If the condenser pressure of the above system is 317 psig, how much subcooling will be required to offset the pressure drop created by the vertical lift?
 
  What will be an ideal response?

Answer to Question 1

The maximum distance between supports for 2 1/8 type L copper is 10 feet.

Answer to Question 2

317  13 = 304 psig. Total subcooling is calculated by determining the saturation temperature of 317 psig R410a that is approximately 100
and the saturation temperature of R410a at 304 psig, which is approximately 97F. 4F of subcooling will be required to prevent flash gas. 100F  97 = 3F + 1F = 4F

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).
