EXPERIMENTAL STUDY ON OPTIMISED COMPOSITION OF WATER BASED NITRATE SALT SOLUTION FOR SENSIBLE HEAT STORAGE

Objective: To find out factors like specific heat, heat capacity and heat loss. Method/Analysis: Sodium nitrate (NaNO3) is mixed in water with different weight quantity like 100g, 200g, 300g last 600g and potassium nitrate (KNO3 ) is mixed in water with weight quantity 100g, 200g, 300g and 400g. Findings: Total heat holding storage is more in NaNO3 than KNO3 , but KNO3 has better energy holding capacity. But KNO3 is reached saturation point in 1 litter water while NaNO3 went up 600g without reaching saturation. Novelty/Improvement: Results shows big molecule has low heat capacity and more Total heat or energy holding storage.
