Sodium nitrate, NaNO3, and potassium nitrate, KNO3, are common salt mixtures used to generate steam in solar towers to produce electricity.

Sodium nitrate, NaNO3, and potassium nitrate, KNO3, are common salt mixtures used to generate steam in solar towers to produce electricity. a. If the conversion efficiency of a solar tower is 18%, what temperature must the salt mixture be raised to if the recycled (waste) salt has a temperature of 230 ◦C? b. Re-calculate the question posed in part a) if the efficiency of the solar tower could be raised to 80%.
