**How Much Water Remains in a 150-Liter Tank After 20% Evaporation?** Why are more people asking, *“A tank holds 150 liters of water. If 20% evaporates, how much remains?”* these days? With rising awareness around water efficiency, conservation, and sustainable resource management, this simple calculation reflects broader concerns—especially in regions where drought and climate variability affect access to clean water. Whether for household planning, agricultural use, or industrial monitoring, understanding water retention after evaporation isn’t just practical—it’s increasingly relevant in everyday decision-making. ### What Happens When Water Evaporates from a 150-Liter Tank? Evaporation is a natural process where liquid turns into vapor, particularly noticeable in warm, dry climates or when containers sit uncovered. In a 150-liter tank, the rate of evaporation depends on environmental factors like temperature, humidity, and surface exposure—but the math behind it remains consistent. If 20% of the stored water evaporates, you’re losing a measurable portion—equivalent to 30 liters—leaving 120 liters behind. This shift isn’t instantaneous; it unfolds gradually depending on conditions, but the outcome is clear and quantifiable.
