//Fluid Systems - By Shiv Kumar //Chapter 17- Dimensional and Model Analysis //Example 17.20 //To Find the Discharge and the Velocity over the Prototype. clc clear //Given Data:- //For Model, Qm=3; //Discharge over the Model, m^3/s Vm=1.5; //Velocity of Flow over the Model, m/s Lr=40; //Scale Ratio (Lp/Lm) //Computations:- //By Froude's Law of Similarity, Vp=Vm*Lr^(1/2); //Velocity of Flow ovre the Prototype, m/s Qp=Lr^2*(Vp/Vm)*Qm; //Discharge over the Prototype, m^/s //Results:- printf("The Velocity over the Prototype, Vp=%.2f m/s \n",Vp) //The Answer Vary due to Round off Error. printf("The Discharge over the Prototype, Qp=%.f m^3/s \n",Qp) //The Answer provided in the Textbook is Wrong.
