HI,
Im having difficulty in a certain aspect of analyzing an Air standard Brayton cycle. Im trying to calculate the effect of change in input energy in the combustor on the velocity at the end of the nozzle. I know the Work of the compressor and turbine and the temperature at the start of the turbine, end of the turbine (same as beginning of nozzle) and end of the nozzle. and from that the enthalpy and entropy at each stage. I cant for the life of me figure out how i can find the velocity at the exit of the nozzle since the only equation that comes to mind is:
(v5)2/2=h4-h5+(v4)2/2
*I also have the velocity at the end of the nozzle for one set of temperatures
