Liquid water is fed to a boiler at 23C under a pressure of 10bar, and is converted at constant pressure to saturated stream. Calculate change in ethalpy for this process and the heat input required for producing 20,000m³/h of steam at the exit conditions. Assume that the inlet velocity of liquid entering the boiler is negligible and that the stream is discharged through a 15cm ID (inner diameter). Inlet and outlet pipes are at the same level. Thanks

Liquid water is fed to a boiler at 23C under a pressure of 10bar, and is converted at constant pressure to saturated stream. Calculate change in ethalpy for this process and the heat input required for producing 20,000m³/h of steam at the exit conditions. Assume that the inlet velocity of liquid entering the boiler is negligible and that the stream is discharged through a 15cm ID (inner diameter). Inlet and outlet pipes are at the same level.
