From the table above, we have succeeded to get the wanted height which is 50.90mm (±0.125mm of 50.80mm). Converting the strength into SI unit, we obtained:

14.8 psi = 0.102 MPa

Graph Weight vs Height

Example of Calculation:

Permeability is calculated by

P= 30557air pressure∈cmof water x time∈(sec)

=30557p x t

P= 30557(10 ×60 )

P=50.928 Percentage error

% error=( (P experimental−Ptheory )P experimental )×100

% error=( (77−50.928 )77 )×100 %=33.86 %
