Oxygen (O2) enters a well-insulated nozzle operating at steady state at 80 lbf/in^2, 11008R, 90 ft/s. At the nozzle exit, the pressure is 1 lbf/in^2 The isentropic nozzle efficiency is 85%. For the nozzle, determine the exit velocity, in m/s, and the exergy destruction rate, in Btu per lb of oxygen flowing.
