Find suitable values of y and x in the equation

[rrab186]

The I/P converter is designed to produce the response 'A' in the graph attached. The balance equation of the system is:

Po=(Kc*y/A*x)*IinKc=2500Newton Amps (NA)
x+y=100mm
z=75 mm
A=5cm^2

Determine suitable values of y and x to give the response 'A' in the graph attached.

pressure must be entered into the equation in pascal and current in amps and all dimensions in metres

The Attempt at a Solution

Po=(Kc*y/A*x)*Iin100000 pascals=(2500*y/0.0005meters^2*x)*0.02

100000/0.02 = (2500*y/0.0005*x)

5000000= (2500*y/0.0005*x)

It is at this point where i am stuck on how to continue and how to make x or y the subject of the equation.

Why don't you try determining the slope from the graph, first.

What part of Po=(Kc*y/A*x)*Iin represents the slope?

Don't forget about your other equation, x+y=100mm
