2. In a system, process stream is heated to a specific temperature and after heating, it is sent to another process. Process stream is fed to the system at 25C and with 15m3/h flow rate. Volume of the tank is 120m3. Density of the fluid is 1g/cm3, heat capacity is 0.8kcal/kg, flow rate of saturated steam is 800kg/h and saturated steam enthalpy is 960kcal/kg. It is known that the heat capacity and density are constant during the heating process. a) Determine the fluid temperature at the exit of the tank when process is steady state? ( F0=F) (10 pt.) b) Calculate the fluid temperature at 5th and 10thh, if the fluid temperature increases suddenly to 65C. (15pt.) c) Flow rate of the saturated steam decreased to 600kg/h due to a technical fault. This fault is noticed after 5h and the flow rate increased to 800kg/h again. Calculate the fluid temperature at 5th and 10thh. (25pt.)
