👉 Fluid, or any liquid, presents several challenges due to its unique properties. It lacks the structural integrity of solids, making it prone to leakage and instability. Liquids are also compressible, meaning their volume can change significantly with pressure or temperature variations, which complicates storage and handling. Additionally, liquids have specific surface tension that can lead to issues like capillary action, where they climb up narrow spaces against gravity. These properties make fluid management complex in various applications, from industrial processes to everyday tasks like cooking and cleaning.
