Liquid water at 19.1 psig and 15°C is heated in a mixing chamber by mixing it with superheatedsteam at 150°C. Liquid water enters the mixing chamber at a rate of 4.3 kg/s and the chamberis estimated to lose heat to the surrounding air at 20°C at a rate of 1200 kJ/min. If the mixture isintended to leave at 80°C please answer the following.a. What should be the pressure at the inlet of the liquid water and the steam to have agood operating mixing chamber? Explain how you arrived to the value and what wouldhappen if values for the inlet streams would be different.b. What should the pressure at the exit of the mixture be under ideal conditions? Why?c. Determine the mass flow rate of the superheated steam.d.Determine the rate of entropy generation in this mixing chamber. Could this mixingchamber operate under the given conditions? Please justify your answer withexplanations.e. If the mixing chamber would have been adiabatic, is there any entropy generation?Perform a computation to support your answer. Would the operation under thoseconditions be feasible?

Since you have posted a question with multiple sub parts, we will provide the solution only to the first three sub parts as per our Q&A guidelines. Please repost the remaining sub parts separately.The liquid water conditions.Superheated steam conditionMixing conditions are as followsTo determine:a)The pressure at the inlet of the liquid water and the steam to have a good operating mixing chamberb)The pressure at the exit of the mixture is slightly less than the inlet pressure c)The mass flow rate of the superheated steam and mass flow rate of the mixtureThe pressure at the inlet of the liquid water and the steam in a mixing chamber must be equal so that the cavitation and flashing is prevented within the mixing chamber. Cavitation occurs when the pressure of a liquid falls below its vapor pressure, causing bubbles to form. Flashing occurs when a liquid boils rapidly due to a decrease in pressure. Both cavitation and flashing can damage the mixing chamber and reduce its efficiency.To ensure that the pressure at the inlet of the liquid water and the steam is equal, the mixing chamber should be designed to operate at a pressure that is greater than the vapor pressure of water at the highest temperature of the inlet streams. In this case, the highest temperature of the inlet streams is 150°C, which corresponds to a vapor pressure of 4.83 psi. Therefore, the mixing chamber should be designed to operate at a pressure greater than 4.83 psi.If the pressure at the inlet of the liquid water is too low, cavitation may occur. Cavitation can erode the mixing chamber and reduce its efficiency. If the pressure at the inlet of the steam is too high, flashing may occur. Flashing can also erode the mixing chamber and reduce its efficiency.In conclusion, it is important to design the mixing chamber to operate at a pressure that is greater than the vapor pressure of water at the highest temperature of the inlet streams in order to prevent cavitation and flashing.Hence the pressure at the inlet of the liquid water and the steam to have a good operating mixing chamber= 4.8PsiThe pressure at the exit of the mixture will typically be slightly lower than the pressure at the inlet of the mixing chamber.In an ideal mixing chamber, the pressure at the outlet should match the pressure at the inlet, indicating no pressure losses. However, real-world conditions introduce friction and other factors that inevitably cause pressure losses. Consequently, the outlet pressure typically falls slightly below the inlet pressure.So, the pressure at the exit of the mixture is slightly less than the inlet pressure .Apply energy balance equation a)The pressure at the inlet of the liquid water and the steam to have a good operating mixing chamber= 4.8Psib)The pressure at the exit of the mixture is slightly less than the inlet pressure c)mass flow rate of the superheated steam= 0.491kg/s and mass flow rate of the mixture= 4.791 kg/s.
