A steam nozzle receives steam at 40 bar and 400°C at an initial velocity of 40 m/s. The final pressure of steam is 10 bar. The mass flow rate of steam is 2 kg/s. The nozzle efficiency is 90%. The cross-section of the nozzle is circular. The angle of divergence is 6°. Calculate the throat and exit diameters and the length of divergent portion. Show the representation of process on h-s diagram and sketch the nozzle and label the dimensions calculated.
