To determine how many gallons of seawater will be displaced when 200 pounds of live rock is submerged, you would first need to know the rock's density. Generally, live rock has a density of about 0.5 to 0.8 grams per cubic centimeter. Assuming an average density of 0.6 g/cm³, 200 pounds (approximately 90.7 kg) of live rock would displace about 30 gallons of water. Therefore, when submerged, around 30 gallons of seawater will be displaced from the 135-gallon reef tank.
Mass = (Density)/(Volume) Make sure you convert your density to gallons.
The answer depends on 14.5 gallons of what, and where. I would guess that in mid ocean, 14.5 gallons of seawater would be worth very little.
GALLONS As in: 1 gallon, 2 gallons.
One gallon of seawater contains approximately 3.5% salt by weight, which translates to about 2,640 teaspoons of salt. This means there are roughly 93 teaspoons of salt in one gallon of seawater. However, the exact amount can vary depending on the location and specific salinity of the seawater.
There are two half gallons in a gallon.
Fill the 5 gallon jug Pour from the 5 gallon to fill the 3 gallon jug You now have 2 gallons in the 5 gallon jug Empty the 3 gallon jug Pour the 2 gallons from the 5 gallon jug into the 3 gallon jug Fill the 5 gallon jug Pour from the 5 gallon jug to fill the three gallon jug -- this will tale 1 gallon You now have 4 gallons in the 5 gallon jug
fill the 7 gallon bucket, dump it into the 5 gallon bucket and save the remaining 2 gallons, repeat and you have 4 gallons.
Two half-gallons = 1 gallon
A gallon
The conversion from UK to US gallons is: UK gallons x 1.201 = US gallons
Multiply Imperial gallons by 1.2 to get US gallons.
Since there are 4 quarts to the gallon - The answer is 4 gallons !
