In general

Type 5 is contour block that has functional relationship:

[math]F_1(u) = F_2(x,v). \,[/math]

This type of block is used commonly in nomographs that have an equation in form

[math]f_a(a_1,a_2,a_3,...) = f_b(u,v) \,[/math]

and [math] f_b(u,v) \,[/math] cannot be represented as line-nomograph. Typically equation above is written as pair of equations:

[math]f_a(a_1,a_2,a_3,...) = x \,[/math]

and

[math] f_b(u,v) = x. \,[/math]

This equation is written in form

[math]F_1(u) = F_2(x,v). \,[/math]

in order to construct this contour block. In reality block consists of horizontal lines:

[math]F_1(u) = y \,[/math]

and contour lines

[math]F_2(x,v) = y, \,[/math]

where x and y are the coordinates of canvas. Coordinate x is reference with name wd in block parameters and it holds

[math]x = f_{wd}(wd). \,[/math]

Simple example

In the following example

[math] F_1(u)=u \, [/math]

and

[math] F_2(wd,v)=wd+v. \, [/math]

Thus the original equation is

[math] wd=u-v. \, [/math]
