200 views

Calculate water flow per hour using the formula: Flow Rate (Q) = Area (A) x Velocity (V). Measure the pipe's cross-sectional area (A) in square meters (m²) and the velocity of water (V) in meters per second (m/s). Multiply these values to get the flow rate in cubic meters per second (m³/s). To convert to liters per hour, multiply by 3,600,000 since 1 m³ = 1,000 liters.

FAQs & Answers

  1. What is the flow rate of water? The flow rate of water is the volume of water that passes through a point in a system over a period of time, typically measured in liters per hour or cubic meters per second.
  2. How do I measure the velocity of water? You can measure the velocity of water using flow meters or by using the time taken to fill a known volume of water to derive the speed.
  3. Why is it important to know the water flow rate? Knowing the water flow rate is essential for efficient plumbing design, ensuring proper irrigation, and optimizing water usage.
  4. Can I convert flow rates between units? Yes, you can convert flow rates between units such as cubic meters per second and liters per hour using appropriate conversion factors.
