Two questions for the engineers in the crowd...
First, what figure would you put on the pressure at the level of the lungs of a
large, submerged, snorkeling _Brachiosaurus_ individual with the lungs about 20
feet (a tad over 6 meters) below the water level? Can this be put in terms of
(pounds per square inch)? I'd appreciate seeing how you arrived at this, and
you're not doing my homework. I'm not enrolled in school at this time. I
understand that the water pressure would be too much to enable the lungs and air
sacs to expand, but I would like to see the predicament quantified.
Second, it has been stated recently on this list that a fast running
rex_ individual (was it 20 meters per second?) would trip and fall on its skull
with the force of a bus impacting a brick wall at approximately 60 mph. I
understand such a hypothetical tyrannosaur was calculated to have sustained
injuries. My question: is the 60 mph bus analogy apt?
