Flowmeters

	The Venturi Meter is another Device used to find the Velocity of a Fluid.
	The parameters for the model include density of fluid (dg), density of manometer liquid (dm),
	differential head (h) .
	Introduction to Solving Venturi Meter Model
	This model is used to find the velocity and discharge of the fluid flowing through the conduit.
	For Loading the Model, press the Button named 'Load the Venturi meter Model'.
	Input :
	Gravitational Accelaration(g)
	Difference in Height in Arms of Manometer Tube(h)
	Density of Manometer Fluid(dens1)
	Density of Fluid(den)
	Diameter of pipe(D1)
	Diameter at Throat(D2).
	Output:
	Fluid Velocity(u)
	Discharge at the end of the Pipe(Discharge)
	Cross Sectional area at End of Pipe(A1)
	Cross Sectional area at Throat(A2).
	In the following cases the venturi meter diameter are kept constant.
	Case 1 : Evaluate Velocity of the fluid with manometric heads for the pipe flow with constant
	fluid density.
	For constant values of g, den, dens1, D1, D2,
	values of h can be changed and the output values for Fluid Discharge and Fluid Velocity can be found.
	eg:   for values of g = 9.8 m/s^2, den = 13.6*10^3 kg/m^3, dens1 = 1000 kg/m^3, D1 = .5 m, D2 = .25 m,
	and h = .4 cm,
	Result: u = 1.07 m/s, Discharge = 2.11E-1 m^3/s
	Case 2 : Evaluation of Flow Velocity for the pipe flow with different fluid density.
	For constant values of g, h, D1, D2,den,
	values of dens1 can be changed and the output values for Fluid Discharge and Fluid Velocity can be
	found.
	eg:   for values of g = 9.8 m/s^2, den = 13.6*10^3 kg/m^3, h = .4 cm, D1 = .5 cm, D2 = .25 m,
	and dens1 = 1000 kg/m^3,
	Result: u = 1.07 m/s, Discharge = 2.11E-1 m^3/s
	Case 3 :    Effect of Changing Density of Manometric Fluid on the Sensitivity of fluid
	Velocity.
	For constant values of g, den, dens1, h, D1, D2,
	values of D2 can be changed and the output values for Fluid Discharge and Fluid Velocity can be found.
	eg:   for values of g = 9.8 m/s^2, dens1 = 1000 kg/m^3, h = .4 cm, D1 = .5 cm, D2 = .25 m
	and  den = 13.6*10^3 kg/m^3,
	Check for the results.
