dmaz is on a distinguished road
Hi, I'm going to conduct some experimental test on a steam turbine.
I have a question about the propagation of the errors on the enthalpy diagram (TS).
I measure the pressures and the temperatures whit the instrumentation but I have to gather the Enthalpies by reading them in the TS diagram.
How would be the percentage of error on the enthalpy if I had an 1% of error in both the measures of pressure and temperature?
Thanks.
Dmaz
