A fluid is fed to a heating tank at a steady state at 20 C with a flow rate of 20 m3/h. The fluid in the tank is heated to a certain temperature with saturated steam at 100 C passing through a serpentine pipe, and after being heated, it is sent to another process with a flow rate of F. It is known that the density and heat capacity of the fluid do not change much during heating. The volume of the tank is 100 m3. The density of the fluid is 1000 kg/m3 and the heat capacity is 0.8 kcal/kgC. The flow rate of the saturated steam stream is 1000 kg/h and its enthalpy is 640 kcal/kg. a) What is the temperature of the fluid at the exit of the tank when the process is stationary? b) The temperature of the fluid in the feed suddenly rises (t=0) to 50 C and the feeding continues at this value. Solve the time variation of the fluid temperature (T) at the process outlet. c) Due to the disruption in the process, the saturated steam flow rate suddenly drops to (t=0) 500 kg/h and feeding continues at this flow rate. How can this 500 kg/h loss be compensated due to the malfunction, what should be done in order to make the flow of the system 1000 kg/h again? d) Due to the disruption in the process, the saturated steam flow rate suddenly drops to (t=0) 500 kg/h and the feeding continues at this flow rate. Solve the time variation of the fluid temperature (T) at the process outlet. e) Draw the block diagram of the system.
