If you consider the fuselage a cylinder and calculate the surface area of the lateral surface it’s 2pir*h. this site has the length as 209.08ft and the diameter as 20.3. That means the fuselage surface area is about 13300ft^2. That same site lists the wing surface area as 4605ft^2, for a total of 17905 square. Assuming an 1/8” of water accumulates uniformly, which is a bad assumption, that’s 2238 cubic feet of water. Each cubic foot weighs about 62 pounds, so that much water weighs 136000 pounds. The normal takeoff weight of a 777 is 534000 pounds, yeah that is a lot. However, only about half the surface area is exposed to rain and 1/8 inch is a lot. Id imagine it’s less than half that weight.
Thats like 2.5 times the weight of fuel when full. Math is bad
It’s the upper bound of a plane fully covered with an eighth inch of water. Reading is hard.
Youre probably the same kind of student I was. Shows that you know how to do the work, but don't care enough to actually find the right answer
Hell yes lol nailed it. I feel seen
I'm even worse at math than either of you, what's bad here?
I appreciate this answer. The other posts showing the math are still cool, but in theory I could do it myself.
You highlighted shit that wouldn't occur to me.
