Thank you for this answer. Actually, I did the double check, that was my first step and also the reason why I'm asking here since I was told that the uncertainty was option 1 in my previous post. But it turns out, unless I did a mistake somewhere in my test program, that option 1 is not the...
You need to estimate what is the positive buoyancy of your pump station.
Without this number, how do you want to calculate the amount of concrete needed ?
1300 km/m^3 is the exact answer for concrete apparent density in seawater. This is Archimede :)
Once again, you also need to know if there...
HI everyone,
Imagine we are sampling of a gaussian signal along time and need to know the power/variance associated with the first N spectral components. So we take our favorite fft algorithm to get the PSD.
The error associated with a given estimated spectral component f(w) (w is the...
Hi,
I guess the pump has a negative buoyancy in water, so it will stay at the bottom even if there is no concrete.
The buoyancy of concrete in water is simply 2300(conctete)-1000(water)=1300 kg m^-3
You may also need to take pressure forces due to currents (if any) acting on the pump.
