Wet steam at a pressure of 2MN/m² flows through a pipe 20m long. The pipe has an external diameter of 80mm. The pipe is covered with lagging 35mm thick which has a coefficient of thermal conductivity of 0.065W/mK. The heat transfer coefficient is 4.5W/m2K and the ambient temperature is 15°C. The steam flow rate is 300kg/h and it enters the pipe with a dryness fraction of 0.97. Assuming there is no temperature drop across the pipe, determine: 3.1 the dryness fraction of the steam as it leaves the pipe;
