Flow Rate Calculator (m³/hr)
Understanding Flow Rate Calculations
The Formula
Flow Rate (m³/hr) = (Volume in liters × 3600) ÷ (Time in seconds × 1000)Step-by-Step Calculation
Convert Liters to m³
1 m³ = 1000 liters → Divide volume by 1000
Volume (m³) = Volume (L) ÷ 1000Convert Seconds to Hours
1 hour = 3600 seconds → Divide 3600 by time
Rate (per hour) = 3600 ÷ Time (sec)Practical Example
20 liters collected in 8 seconds:
(20 × 3600) ÷ (8 × 1000) = 72,000 ÷ 8,000 = 9 m³/hrCommon Mistakes to Avoid
Using inconsistent units (e.g., minutes instead of seconds)
Not accounting for measurement errors in small time intervals
