a. Two streams of water are mixed to form the feed to a boiler. Process data are as follows: 120 kg/min at 30 °C 175 kg/min at 65 °C 17 bar (absolute) Feed A Feed B Boiler pressure The exiting stream emerges from the boiler through a 6 cm ID pipe. Calculate the required heat input to the boiler in kJ/min if the emerging stream is saturated at the boiler pressure. Neglect the kinetic energy of the liquid inlet streams.
