+//Given Data:-
+ W=55.50; //Weight of plate, N
+ V=8; //Velocity of the Jet, m/s
+ d=22; //Diameter of the Jet, mm
+ AG=125; //Distance between centre of gravity of plate from hinge, mm
+ AC=150; //Distance between axis of Jet and hinge, mm

+//Data Used:-

+//Computations:-
+ d=d/1000; //m
+ AC=AC/1000; //m
+ AG=AG/1000; //m
+ a=(%pi/4)*d^2; //cross sectional area of Jet, m^2
