+//Given Data:-
+          //For Model,
+             H_mM=7.5;       //Manometric Head, m
+             Nm=1000;        //Speed, rpm
+             Pm=25;          //Shaft Power, kW
+        
+        //For Prototype,
+             H_mP=23;           //Manometric Head, m
+
+      Dm_by_Dp=1/6;             //Scale Ratio
+
+
+//Computations:-
+      
+         // (a)Working Speed of the Prototype, Np 
+           Np=Nm*Dm_by_Dp*sqrt(H_mP/H_mM);       //rpm
+
+       // (b)Shaft Power of the Prototype, Pp
+              Pp=Pm*(Np/Nm)^3*(1/Dm_by_Dp)^5;           //kW
+
+       // (c)Ratio of Flow Rates handled by the protoytpe and the Model, Qp/Qm
+          Qp_by_Qm=(Np/Nm)*(1/Dm_by_Dp)^3;

+          printf(" (a)Working Speed of the Prototype, Np =%.2f rpm\n",Np)       //The answer vary due to round off error
