Question

A nozzle is a device that converts fluid thermal energy and enthalpy into kinetic energy. The kinetic energy may be used to drive a mechanical devise such as turbine wheel, thus converting the fluid energy into mechanical work. Steam flows at a steady state through a converging, insulated nozzle, 25 cm long and with an inlet diameter of 5 cm. At the nozzle entrance, the temperature and pressure are 325 ◦C and 170 kPa respectively, with a velocity of 30 m/s. At the nozzle exit, the steam temperature and pressure are 240 ◦C and 350 kPa, respectively. Property values are stated below. Determine the exit velocity from the nozzle and the exit diameter.

H₁ = 3112.5 [kJ/kg] H₂ = 2945.7 [kJ/kg] V₁ = 388.61 [cm³/g] V₂ = 667.75 [cm³/g]
