913 A kilogram of steam at a pressure of 1·0 × 10° N/m? and a temperature of 250 °C is contained in a cylinder closed by a piston. The steam is compressed by the motion of the piston inwards until the pressure is 2-0 x 10$ N/m2. The work done on the steam is 610 x 103 Nm and the heat transfer from the steam is 890 x 10 J. Find the final steam temperature if the steam is superheated, or the dryness if it is wet. 913 A kilogram of steam at a pressure of 1·0 × 10° N/m? and a temperature of 250 °C is contained in a cylinder closed by a piston.
