Question

What is the range of range of the water, which comes from degrees of salinity?

(a) 300 – 8000 ppm

(b) 4500 – 50,000 ppm

(c) 70000 – 85000 ppm

(d) 3000 – 280,000 ppm

The question was posed to me in class test.

This key question is from Hydrothermal Systems topic in portion Ocean Energy & Geothermal Energy of Energy Engineering

Answer 1

The correct choice is (d) 3000 – 280,000 ppm

For explanation: The water comes with various degrees of salinity, ranging from 3000 to 280,000 ppm of dissolved solids, and at various temperatures. There are, therefore, various systems for converting liquid dominated system into useful work that depend upon these variables.
