"DH 20" could refer to many things depending on the context. It could be a designation for a specific product, a code, a chemical compound, or a research term. Without more information, it's difficult to provide a specific answer.
No. Freshwater does not have the same amount of dissolved materials as sea water. Sea water has a much greater amount of salt dissolved in it.
Sea water is a complex solution.
Sea water is the densest among river water, distilled water, tap water, and sea water. This is due to the higher concentration of salt and minerals in sea water, which increases its density compared to the others.
I would imagine that the sea water would have to run through a water purifier.
The Norco team DH is better
Once the DH moves to a defensive position the DH is no longer allowed in the lineup. In that case, the pitcher would assume the position in the batting order of the defensive player replaced by the DH.
When their is a AL team is the home there is a dh. When a NL team is the home team there is no dh.

Yes. The DH hits for the pitcher and if the DH enters the field of play the pitcher then has to hit for himself
The Arabic symbol that is commonly transliterated as "dh" is ذ
1 DH is 8.18 Maurition rupee.
Once the DH takes a defensive position in the field, his team can no longer use a DH.
Yes. There is no obligation to use the DH in baseball. A somewhat confusing question. A relief pitcher can be used AS the DH. However normal DH rules apply and that player could not pitch in the game. A relief pitcher can pinch hit FOR the DH as well. That pitcher then becomes the DH and normal rules apply. I am pretty sure that a relief pitch that enters the game as a pitcher can not be inserted into the lineup for the DH but I could be wrong. Of course you don't have to use the DH but you can't use a relief pitcher in your lineup unless he's playing a position in the field. Yes. When you bring in the relief pitcher, you can at that time have him hit in place of the DH. You can also have him pinch-hit for the DH at a later point in the game. Note that in both cases, there is no longer a DH and all pitchers must hit. Baseball rule 6.10.
