chloride concentration of the water (Table 13-1). Using this concentration, one 

 can obtain the resistivity of the water at the desired temperature directly from 

 the curve in Figure 13-5. Close agreement can be obtained between the calcu- 

 lated and measured resistivity on the same water sample.
