4. Steam enters a cylinder fitted with a piston at a pressure of 20 MN/m² and a temperature of 500 deg C. The steam expands to a pressure of 200 kN/m² and a temperature of 200 deg C. During the expansion there is a net heat loss from the steam through the walls of the cylinder and piston of 120 kJ/kg. Determine the displacement work done by one kg of steam during this expansion.

4. Steam enters a cylinder fitted with a piston at a pressure of 20 MN/m² and a temperature of
500 deg C. The steam expands to a pressure of 200 kN/m² and a temperature of 200 deg C.
During the expansion there is a net heat loss from the steam through the walls of the cylinder
and piston of 120 kJ/kg. Determine the displacement work done by one kg of steam during
this expansion.
