Hi, I've a problem with App V, especially with formula V.8.1.3.
If the value of Ps=W+.4Pe and greater then Pe (i.e. Pe=0.5kPa), do you use ? of condition 1 of V.8.1?
Hi,
I've also a problem with App V, especially with formula V.8.1.3.

Thanks for your answer, but could you explain why the units from the first formula are N/m and the second one are m^2? Or have they considered this difference in the constants 59 and 140.8( calculated value for 0.9 in metric units)?
Hi,
I'm struggeling with the same problem as you xema77.
1) yes indeed ,if you multiplie the tank circumference and wl, you get the liquid weight.
(I assume that because, in API 650 edition 10 ad4,in formula E-23, wa is also computed for the tank circumference)
2) did you have already found...
