Example only. This sheet shows one way to set out the check. It is not endorsed by the bodies that publish the design codes and does not reproduce them. Check every clause, value and assumption against your own copy of the current edition of your references and the codes that apply before you use it, and have the result checked by a competent person. See the disclaimer.
The calculation, line by line
Every line below is typed into Equation Pad exactly as shown; the app typesets it, works out the value with its units and shows checks as TRUE or FALSE. Change any input and everything below it updates.
# Clay layer
H_c := 4 m
c_v := 2 m^2/year
T_v90 := 0.848
# Time
H_dr := H_c/2 = m
t_90 := T_v90*H_dr^2/c_v = year
# With drainage at one face only, H_dr = H and the time is four times longer.How to use this example
