+//Fluid Systems - By Shiv Kumar
+//Chapter 17- Dimensional and Model Analysis
+//Example 17.21
+//To Find the  Ship Velocity and Propulsive Force in the Prototype.

+     clc
+     clear
+
+//Given Data:-
+       //For Model,
+           Lm=1;     //Length of Model, m
+           Vm=0.7;    //Speed in the Model, m/s
+           Fm=5;     //Force in the Model, N
+           
+      //For Prototype,
+           Lp=50;        //Length of Prototype, m
+  
+
+//Computations:-
+         //By Froude's Law of Similarity,
+             Vp=Vm*(Lp/Lm)^(1/2);       //Velocity of the Prototype(Ship), m/s
+             Fp=Fm*(Lp/Lm)^3/1000;       // Propulsive Force in the Prototype, kN
+
+
+//Results:-
+       printf("The Ship(Prototype) Velocity , Vp=%.2f m/s \n",Vp)
+       printf("The Propulsive Force in the Prototype , Fp=%.f kN \n",Fp)
