M = mass (kg)
t = time (s)
ρ = density (kg/m3)
q = volume flow rate (m3/s)
V = volume (m3)
γ = specific heat ratio
cf = fluid capacitance (m5/N)
D = effective diameter (m)
μ = viscocity ((N*s)/m2)
L = effective length (m)
p = pressure (N/m2)
P0 = initial pressure (N/m2)
Pa = atmospheric pressure (N/m2)
Rf = fluid resistance ((N*s)/m5)
τ = time constant (s)
