A cylindrical tank with a radius of 3 meters and a height of 5 meters is filled with water. Water is drained at a rate of 2 cubic meters per minute. How long will it take to completely drain the tank? In today’s increasingly water-conscious landscape, stories about large storage tanks—especially cylindrical ones—have gained quiet traction. This particular tank holds 141.37 cubic meters of water, calculated using the formula for the volume of a cylinder: π × r² × h. At a consistent drain rate of 2 cubic meters per minute, users naturally wonder how long it takes for the tank to empty completely. As shared across platforms focused on practical trends and technical literacy, this scenario reflects common concerns about water management in industrial, municipal, and agricultural settings. What begins as a simple question opens a doorway to understanding flow dynamics, resource economics, and infrastructure efficiency. This tank’s volume equates to about 141.37 cubic meters—roughly the size of a small swimming pool—but its cylindrical shape means water drains predictably and uniformly. At 2 cubic meters drained every minute, the math is straightforward: 141.37 ÷ 2 ≈ 70.69 minutes, or just over an hour and six minutes. Yet real-world variables like pressure, outlet design, and sediment can subtly influence actual run times—the tank rarely empties in perfectly linear intervals. Still, this predictable rate offers a reliable baseline for planning and resource tracking. Why is this kind of query rising in mobile searches? Beyond emergency scenarios, people encounter this situation while exploring water storage options, assessing system maintenance, or investigating infrastructure resilience. The topic aligns with growing interest in water efficiency, sustainability, and supply reliability. As users seek clarity, they’re matching the primary keyword naturally, reinforcing strong SEO potential for SERP #1.
