Measurements with small freshwater sponges such as Grantia have documented water flow rates around 3–4 ml/minute.
Assuming that a sponge has a constant flow rate over the course of a day, how many ml of water could a single sponge such as Grantia filter in a 24-hour period?
4320 - 5760 milli-litres with 5040 millilitres on average...
Explanation:
There are 1440 minutes in a day. If the rate of flow is 3 to 4 millilitres per minute then an average of 5040 millilitres or 5.040 litres shall be flowed out.
