A method based on the concept of eddy viscosities due to turbulence and bubble agitation is utilized along with appropriate correlations available in the literature in order to estimate the total pressure drop in a vertical bubbly flow. The method aims to minimize the experimental measurements required to calculate the pressure drop which remains the most significant quantity of engineering interest in fluid flows. It has been shown in this work through experimental comparisons that these correlations can make the procedure independent from the knowledge of experimental measurements and yet are able to estimate the total pressure drop with good accuracy.
