+//Given Data:-
+         Q=0.118;      //discharge, m^3/s
+         N=1450;        //Speed, rpm
+         Hm=25;        //Manometric Head, m
+         Do=250;         //Diameter of the Impeller at Outlet,  mm

+         eta_man=75/100;         //Manometric Efficiency

+//Data Used:-
+         g=9.81;        //Acceleration due to gravity, m/s^2
+
+//Computations:-
+          Do=Do/1000;        //m

+//Results:-
