Experiments are being designed to measure the horizontal force F on a fireman’s nozzle, as shown in Fig. P7–112. Force F is a function of velocity V1, pressure drop ΔP = P1 – P2, density r, viscosity μ, inlet area A1, outlet area A2, and length L. Perform a dimensional analysis for F = f (V1, ΔP, ρ, μ, A1, A2, L). For consistency, use V1, A1, and r as the repeating parameters and generate a dimensionless relationship. Identify any established nondimensional parameters that appear in your result.
