Question 93General Subjects - 1st Asst/Chief
70% to passA salinity indicating system functions on the basic principle of measuring the _______________.
Ahydrogen ion concentration of water
Bspecific gravity of water
Celectrical inductance of water
Delectrical conductivity of water
AI Explanation
The correct answer is D) electrical conductivity of water. A salinity indicating system functions on the basic principle of measuring the electrical conductivity of the water. The electrical conductivity of water is directly related to the amount of dissolved salts or minerals in the water, which is known as salinity. By measuring the electrical conductivity, the salinity of the water can be determined. The other options are incorrect because: A) Hydrogen ion concentration (pH) is not directly related to salinity. B) Specific gravity is not the primary factor measured by a salinity indicating system. C) Electrical inductance is not the principle used to measure salinity.
