In dimensional analysis, it is assumed that the phenomenon can be expressed by a dimensionally homogeneous equation with certain variables.
Different physical quantities which are used in fluid phenomenon are formed by some fundamental quantities or primary quantities such as mass, length, time and temperature.
To find dimensions of force,
Force = Mass x Acceleration
F = Mass x (Length / Time
2
)
F = M x (L / T
2
)
F = [M L T
