After some research through internet I found out they use quartz glass instead of normal one so the UV light can pass through it.

You can use the following formula to get pressure at certain depth: (hmm for some reason I can't get tex working) p = p0 + rho * g * h where p0 = initial pressure, in this case 1 bar rho = density of water = 1000 kg/m3 g = gravity acceleration = 9.81 m/s^2...

It's turbulent for any Re > 4000. The calculation of Re number depends on what type of flow it is. For open systems (such the wing is in this case) you have to use hydraulic radius instead of charasterictic length used in pipe flows. There is a wikipedia article how to calculate certain flows...

Basically what you have done is a polar coordinate construction of rectangle that's centered at origin It's a quite more complicated way to represent rectangles but nonetheless interesting. There is an error though, you could try plugging in \pi/6 for the formula and you get the wrong answer...
