A cylindrical tank with a radius of 5 meters and a height of 10 meters is filled with water. If water is pumped out at a rate of 2 cubic meters per minute, how long will it take to empty the tank completely?
In a growing number of conversations across homes, urban infrastructure, and industrial facilities, a practical question continues to surface: how long does it really take to drain a large cylindrical water tank—like the one measuring 5 meters in radius and 10 meters tall? With rising awareness around water management, energy-efficient pumping systems, and sustainable infrastructure, this seemingly simple calculation connects to real-world needs—from municipal water supply planning to commercial facility operations. Understanding how long such a tank takes to empty under steady pumping reveals valuable insights not only for maintenance scheduling but also for broader discussions on resource conservation and system design.
Why This Tank Is Making Headlines in the US
Understanding the Context
Behind this practical query lies a quiet shift in public and professional interest. As cities invest in resilient water distribution networks and industries optimize resource use, cylindrical tanks of these proportions—5m radius, 10m height—represent both scale and efficiency. The volume of water held, approximately 785 cubic meters, places them firmly in the category of large-capacity storage essential for balancing supply and demand. With water pressure and drainage speed directly tied to output rate, this scenario emerges naturally from real-world operations in utilities, agriculture, and manufacturing.
Why is someone eager to know how long it takes to empty one of these tanks? A clear answer supports better emergency planning, maintenance scheduling, and operational transparency—especially when costs, safety, or resource continuity depend on accurate timing.
How a Cylindrical Tank with a 5m Radius and 10m Height Is Drained
Calculating how long it takes to drain the tank hinges on two pieces of core data: volume and pumping rate. Volume equals π × radius² × height. With a radius of 5 meters, the base area is about 78.54 square meters. Multiplying by a height of 10 meters gives a total capacity of approximately 785.4 cubic meters. When water is pumped out at 2 cubic meters per minute, the time to empty the tank is found by dividing total volume by the flow rate.
Key Insights
785.4 ÷ 2 = 392.7 minutes
This means it takes roughly 392.7 — or just under 6.5 hours — to drain the tank completely under steady pumping at 2 m³/min. This clear, math-backed timeline helps demystify what might otherwise feel like an abstract calculation
