The simplest use of centrifuges to measure soil properties relies on steady state conditions. Analytical solutions, especially if they are simple, make interpretation of data more direct and transparent. Previous approximations are simplified and have a greatly improved accuracy. Using previous examples as a test, the error on pressure is always less than 1%, compared to about 10% with previous approximations.
