regarding equations and parameters shown in the below figures write a MATLAB code programming for venturi flowmeter calculation.

A fluid passing through smoothly varying constrictions experience changes in velocity and pressure. These changes can be used to measure the flowrate of the fluid. To calculate the flowrate of a fluid passing through a venturi, enter the parameters below. (The default calculation involves air passing through a medium-sized venturi, with answers rounded to 3 significant figures.) As long as the fluid speed is sufficiently subsonic ( V3000 in pipes), f is determined from experimental curve fits. One such fit is provided by Colebrook, f1=2log(3.7e1D+Rf251) The solutions to this equation plotted versus R make up the popular Moody Chart for pipe flow
