That would be 14 bar, which we would expect at a reasonable depth in a Jovian atmosphere. This is actually very useful information, as it allows us to factor in drag fairly accurately.I don't know how much it helps, but when the shuttle was first nearing the Klingon ship (before it had descended a lot further into the atmosphere), the pressure was 15,000 GSC. I assume that means 15,000 grams per square centimeter. That would work out to 213.29 pounds per square inch, for whatever that's worth.
More critical than the 500 meter photon torpedo, however, is the earlier, less effective torpedo, for which we have better numbers:
More precise figures:What was that?
Weapons fire.
Where?
Bearing 297 mark, 261,
down about two kilometers.
REED:
Did it work?
We've moved up,
but only 200 meters.
Raptor: 145m length (EAS), 115m wingspan. 6413 sq m area from beneath (GIMP). I would put mass at 100,000-200,000 metric tons myself, giving a gravitational potential increase of 6 +/-2 x 10^11 joules (x 20 m/s/s, x 200 m) and an initial velocity of 89 m/s. Assuming that the Raptor absorbed 100% of the blast energy passing through, and noting
this is 1/7838th the area of a 2 km radius blast, we get total blast energy of 4.7 +/- 2.4 x 10^15 joules. Blast energy is usually around half the total yield.
This is neglecting air resistance. Doing a quick numeric integration with a spreadsheet, using 14 bars of atmospheric pressure and noting that the Raptor is nearly completely unaerodynamic in that position, I get an actual initial velocity of around 94 m/s (with a flight-to-peak time of around 6 seconds), meaning 12% more energy.
A reasonable off-the-cuff estimate would then be 2.5 +/- 0.8 megatons for the yield. This is still significantly low, however, unless previously unmentioned technobabble allow the Raptor to fly with 100% of the blast energy impacting it. I'll go into details on exactly how much we can expect to be transmitted another day, however, since I've spent long enough already writing this.
As a quick consistency check, the Raptor should absorb 16x as much energy and therefore fly 4x the initial speed, which is in the right neighborhood for a 22 second flight from the closer photon torpedo.
