It is impossible to install a water 552 Chapter 31--SteAm Heating Systems gage glass on an; inverted bucket trap, but if visual inspection is necessary, a gage glass can be placed on the line leading to the trap.

In a reversed return system, the water returns to the heater by an indirect route after it has passed through the radiators, so that the paths leading through the three radiators shown in Fig. 2 are practi cally of equal length. 602 Chapter 33--Hot Water Heating Systems and Piping The reversed return system has an advantage over the direct return system in that it is more likely to function satisfactorily even though the pipe system is not accurately designed.

A comparison between the perfor mance'f two designs, unless based on such tests on each, may lead to entirely erroneous conclusions.

For the present it can be only inferred that bodily discomfort may be an indication of adverse conditions leading to poor health. 3 Given dry-bulb and wet-bulb temperatures of 76 F and 62 F, respectively, and an air velocity of 100 fpm, determine: (l) effective temperature of the condition; (2) effective temperature with calm air; (3) cooling produced by the movement of the air. (1) In Fig. 1 draw line AB through given dry- and wet-bulb temperatures.

We thoroughly discussed the advantages of dribble blend ing and explained that with the use of a special blending valve they could add lead at the rate of 10# per minute, or possibly less.

Among benzene expoeed workers, a five-fold excess of total leukemia and a 10-fold excess of myelomonocytic leukemias were demonstrated even under condi tions leading to an underestimate of the true leukemia risk.
