N2 flows through a nozzle of exit area 0.002 m^2 at a rate of 0.005 kg/s at steady state. the inlet pressure to nozzle is 200 kpa, inlet temperature is 200 c, and exit pressure is 50 kpa, exit temperature is 50 c. find the exit velocity. find the heat loss from the nozzle. hint: use ideal gas equations, write energy equations, take u=cv*t, h=cp*t if required. neglect potential energy changes and inlet velocity to the nozzle.
