It is proposed to use a katharometer to mesaure the amount (about 5%) of oxygen in nitrogen, in the presence of a small amount (0.5%) hydrogen. How constant would the proportion of hydrogen have to be in order to limit errors in measurement of % oxygen to +/- 0.1%?
The thermal conductivities...
The block diagram (attached) shows the control of an electric heating
system. The heater is driven from a voltage-controlled power supply, the
voltage V1 being derived from a potientiometer. The output temperature,
θO, is subject to disturbances, θD, because of changes in the ambient...
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...
