+//Fluid Systems - By Shiv Kumar
+//Chapter 17- Dimensional and Model Analysis
+//Example 17.23
+//To Find the Velocity of the Prototype and Force Required to Propel the Prototytpe.

+     clc
+     clear
+
+//Given Data:-
+         Lr=40;         //Scale Ratio (Lp/Lm) 
+      //For Model,
+             Vm=2;    //Velocity for the Model, m/s
+             Fm=0.5;     //Propulsive Force in Model, N
+     //For Prototype,
+          Lp=45;     //m
+
+
+//Computations:-
+         //By Froude's Law of Similarity,
+             Vp=Vm*Lr^(1/2);       //Velocity for the Prototype, m/s
+              Fp=Fm*Lr^3;       //Force Required to Propel the Prototytpe, N 
+
+
+//Results:-
+       printf("The Velocity of the Prototype, Vp=%.2f m/s \n",Vp)        //The Answer vary due to Round off Error
+       printf("The Force Required to Propel the Prototytpe , Fp=%.f N \n",Fp)
