Nitrogen enter an adiabatic nozzle at $42$ lbf$/$in$2,1360$ oF$,25$ ft$/$s and exits to the

atmosphere. The nozzle operates with an isentropic efficiency of $74\%.$

a$)$ What is the maximum theoretical exit velocity, ft$/$s$,$ for the nozzle?

b$)$ Calculate the actual exit velocity, ft$/$s$.$

c$)$ Determine the entropy generated, Btu$/$lboR$.(0\mathrm{.}018679$ Btu$/$lboR$)$this value is the correct answer to check work with
