(A) A piston-cylinder device initially contains steam at 3.0 MPa, superheated by 16.1°C with a volume of 0.4m ^ 3 . At its initial condition (State 1), the piston (weighing 12445 kg with a diameter of 0.3 m), is 30 cm above the stops at an equilibrium condition. The arrangement is open to an outside pressure of 90 kPa. Determine , () The initial temperature of steam [1] Mass of the steam[1] () Force balance diagram at this condition [1] (iv) Total enthalpy and Total internal energy (kJ) [2] (Bthe moves
