A stream of saturated steam at 1 atm and a flow rate of 1150 kg/h is mixed with a second stream of superheated steam at 400°C in an adiabatic mixing. The resulting stream is a superheated steam at 300°C which is a feed to a heat exchanger. a) Draw a schematic diagram of the process. [2 marks] b) Write the energy balance for the system clearly stating the references and all assumptions. [2 marks] c) Calculate the amount of superheated steam at 300°C produced and the required volumetric flow rate of the 400°C steam. [4 marks] Additional data: Specific volume of superheated steam at 400°C is 3.11 m3 /kg For physical and thermodynamic data use Q1 Table 3 in the Additional Data Section.
