Thrust calculation and ct comparison

[NM1293]

Hello Everyone,
How do you obtain the value of 0.072 for the thrust coefficient from experimental data of Zawodny et al?
The values in the paper are different. I think I am making a mistake with the units.

By using your equation:

Ct = T / (rho * (n^2) * (d^4))

with:

Ct = 0.066 (from mid-high fidelity)
rho = 1.071778 kg/m^3
n = RPM/60 = 5400/60 revolutions/s
d = 0.24 m

I am getting a thrust of 1.9 N, which seems fine when compared to other sources.
