Liquid water at 24 ºC is fed to a boiler operating at 10 bars and is converted at constant pressure to saturated steam.  The steam is produced at a steady state flow rate of 15,000 m3/hr.  Assume that the kinetic energy of the liquid entering the boiler is negligible, and that the steam is discharged from the boiler through a 15 cm diameter pipe.  

  1. What is the temperature of the saturated steam (ºC)?
  2. Calculate ∆Ĥ (in units of kJ/kg) for this process.
  3. Calculate the heat input (kJ/hr) to meet the needed saturated steam production rate.
