Steam flows through a pipe at a rate of 400 liters/min, with a pressure of 5 atm (gauge) and temperature of 400°C. The steam pressure decreases to atmospheric pressure, and the recorded temperature is 350°C at one end of the pipe (Point 2). The barometer inside the plant gives a reading of 757 mm Hg.  Calculate the volumetric flow rate of this steam at this Point 2.
