The model produces a quantity with inconsistent or wrong units, or mixes unit systems, yielding a dimensionally invalid result. The rule
A tank fills at 3 L/min for 4 minutes, then drains at 500 mL/s for 10 seconds. Net litres?
To find the net litres, we first need to calculate the amount of liquid filled and then subtract the amount drained. Filled amount: The tank fills at 3 L/min for 4 minutes. So, filled amount = 3 L/min * 4 min = 12 L Drained amount: The tank drains at 500 mL/s for 10 seconds. First, convert the drain rate to L/s: 500 mL/s = 0.5 L/s Then, calculate the drained amount: 0.5 L/s * 10 s = 5 L Net litres = Filled amount - Drained amount = 12 L - 5 L = 7 L Answer: 7 L
detector fmi_4_4_v1: correct unit L
To find the net litres, we need to calculate the total litres filled and subtract the total litres drained. The tank fills at 3 L/min for 4 minutes, so: 3 L/min * 4 min = 12 L The tank drains at 500 mL/s for 10 seconds. First, convert the flow rate to L/s: 500 mL/s = 0.5 L/s Then, calculate the total litres drained: 0.5 L/s * 10 s = 5 L Now, subtract the total litres drained from the total litres filled: 12 L - 5 L = 7 L Answer: 7 L

12 L in, 5 L out, net 7 L. The mixed units are the trap.

Unchanged by context: 0% with none, 0% with the strongest supplied source. For a control mode that flat line is the result — it is what licenses reading movement elsewhere in this loop as grounding rather than as a document being present. Nothing survives at the best condition on the cases measured here.
