The pressure drop across a short hollowed plug placed in a circular tube through which a liquid is flowing (see Fig. P13.10) can be expressed as
![]()
where is the fluid density, and V is the velocity in the tube. Some experimental data obtained with D = 0.2 ft, = 2.0 slug/ft3 , and V = 2 ft/s are given in the following table:

Using suitable dimensionless parameters, plot the results of these tests logarithmically. Use a standard curve-fitting technique to determine a general equation for ∆p. What are the limits of applicability of the equation?
