Phaser yield calculations thread
By: Dutch Date: December 4, 2020, 2:40 pm
---------------------------------------------------------
This is where we put calculations of RW phaser yields. As
always, treat each example as if it happened in RW, with the
same scaling and mechanisms. So, even if ST phasers use an
exotic chain reaction

instead of
raw energy, act like they use the latter like in RW.

Phaser yield by Wiki info
By: Dutch Date: December 4, 2020, 2:45 pm
---------------------------------------------------------
According to a Wiki page, a light phaser shot has the same
explosive power as 35g of TNT. [1] 35g of TNT = 146440 joules.
[2] The energy required to melt 25g of ice at its freezing point
is 8290 joules. [3] So a phaser shot from the DPS New Orleans
can melt 1.76 kg of ice, or melt and vaporize 19 grams of iron.
However, only about 50% of the blast energy will hit the target,
so these numbers are likely high.

Destroyer vaporized

I will assume the Yridian starship is about 4 feet long. I will
also assume that it weighs around 20 kg and is made of iron. To
melt-vaporize 20 kg of iron takes about 152 megajoules, about
two hundred times the maximum yield of a heavy turbolaser.
That's absurd, unless the ship is loaded with explosives. Of
course, it also wouldn't blow up like that.

Enterprise-D vs Borg cube

The first phaser shot appears to vaporize about 600 kg of iron.
4578 megajoules are needed to do that—absurd.

Vaporization of sand

The energy needed to vaporize 1 kilogram of silicon is roughly
13.23 MJ/kg. [1][2] In 1/10 of a second, maybe 20 grams are
vaporized. This requires about 265 joules. So the phaser is
delivering 2650 joules per one-second shot, or 0.63 grams of
TNT.

[2]: I'll assume the sand is made of granite, which is similar
to silicon.

Lysian destroyer destroyed

By destruction: to vaporize 2.5 kg of iron requires roughly 19
megajoules (19000000 joules, or 4.54 kg of TNT). Not possible
for a heavy phaser.
Rating: 7/10
By blast radius: the yield is probably about 188280 joules (0.1
lb or 45 grams of TNT), as the radius is about 2 meters. [1]
Totally possible for a heavy phaser.

To vaporize 300g of iron takes about 2.5 megajoules—2500000
joules. That's 590g of TNT. Not possible, but not crazily absurd
either, especially if the pods' reactors and fuel add to the
explosions. A powerful phaser could melt (not vaporize) 300g.

NX-class hits reactor

The larger explosion is from the ship's exploding reactor. The
smaller one has a radius of about 2 feet, and so is about 22g.
[1] Very realistic. [2]

[2]: The weapon is actually meant to be a phase cannon, but in
RW it best matches the effect of a phaser.

Way-too-slow phaser beam

Looks like it melts the surface, but doesn't vaporize it (the
armor is glowing, but not steaming). Steel glows yellow-white at
about 1200C. [1] Therefore, the energy required is about 90J.
[2] This assumes 100% of the phaser's energy is going to the
armor, but this is clearly not the case. So the beam has a yield
range of about 80-200J.
