A gaseous mixture consists of 75 percent methane and 25 percent ethane by mass. 28,000 m³ of this mixture is trapped in a geological formation as natural gas at 150°C and 14 MPa. This natural gas is pumped 2000 m to the surface. At the surface, the gas pressure is 140 kPa and its temperature is 90°C. Using Kay’s rule and the enthalpy-departure charts, calculate the work required to pump this gas.
