Question 424Steam Plants - Assistant Engineer
70% to passA unit of measure used to express the chloride content of boiler water is _______________.
ApH
BPPM
CMicro-Farads
DMicro-Ohms
AI Explanation
The correct answer is B) PPM. The chloride content of boiler water is typically measured in parts per million (PPM), which is a unit of measure used to express the concentration of a substance in a solution. This is the standard unit used in the U.S. Coast Guard Captain's License Examinations to evaluate the chloride levels in boiler water, as high chloride levels can lead to corrosion and damage to the boiler system. The other answer choices are not correct - pH measures the acidity or basicity of a solution, micro-Farads are a unit of electrical capacitance, and micro-Ohms are a unit of electrical resistance, none of which are directly related to the measurement of chloride content in boiler water.
