Flooding Time - Simple Orifice Estimate
Flooding time through a simple orifice - √(2gh) exit velocity + compartment volume.
Initial flow rate
4.60m³/s
Time to fill (simple)
1.8min
Formula, assumptions, and limits
Simplified - ignores rising internal water level reducing head. Real flooding slows as compartment fills. Automatic detection alarms by bilge level gauges.
