I think they are talking about how much of the potential chemical energy gets converted into work/horsepower....I really wish they expressed it as an efficiency percentage. But I only have one semester of Thermo under my belt and now I am an accounting major so that tells you how good of an engineer I was.:lol3:
A snail would cover a quarter faster then the Oil tankers and cargo ships those motors power....then again I dunno if I would want all that mass moving so quickly... that hitting ya would HURT
That sucker is in the Emma Maersk, 1300 or 1400 ft long , just over 200 ft wide. Loaded she does 31 knts. thats pretter damn fast for a Vessel of any size, other than the Navy.
The US aircraft carriers are one of the fastest Vessels on the water. Ran into a privite contractor for the Navy in Italy a few yrs back. He was a engineer that built the aircraft carriers for the Navy. Over a few beers he was saying that they where capably of 60-70 knots empty. He said they can out run there own escort. now whether that was true or not i dont know, but it sounds good and why not.
I was in the Med on a Carrier during the initial air campaign in 03. I personally witnessed 47 knots on the ships TV. Steam power turning four 30 foot diameter props and fully loaded too. Yes, a carrier will pull away from all the other ships in the battle group.
At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.
with a new turbo I think I would compete in the torque specs.rof:rof
wonder how many gallons of fuel each piston burns in one stroke.
If 102 is max rpm whats it idle at?
I really like the pic with the little ppl putting the bearing in. Seems so unreal like it was photochopped. thanks for looking that up nomod. cool pics:thumbsup
