QUESTION 1 Liquid water is fed to a boiler at 24C and 10 bar, and is converted at constant pressure to saturated steam. 1.1. Use the steam tables to calculate A (kJ/kg) for this process, (20) 1.2. Calculate the heat input require to produce 15000 m3/hr of steam at the exiting conditions. Assume that the kinetic energy of entering liquid is negligible and that the steam is discharged through a 15 cm ID pipe
