Two streams of water are mixed to form the feed to a boiler. The heat into the system is 75,000 kJ/min. The specific enthalpy of the outlet stream is 2973 kJ/kg and its flow rate is 300 kg H2O(v)/min. a) Calculate the combined energy contribution from the two input streams (not the indivual streams). b) Let's say the specific enthalpy of input stream 1 is 300kJ/kg. What is the specific enthalpy of the other stream if its mass flow rate is m2= 250 kg/min?
