Imagine a 1 shell-1 tube pass heat exchanger involving co-current flow of hot and cold streams, both of which are in liquid phase. The convective heat transfer coefficients on the tube and shell sides are ht, and hs, respectively. The tube thermal conductivity is kw. The inlet and exit temperatures of the hot and cold streams are as follows: inlet temperature of the hot stream is 90C, inlet temperature of the cold stream is 30C, exit temperature of the hot stream is 65C, exit temperature of the cold stream is 45C. a) Draw the temperature profile for this heat exchanger. b) Draw the temperature profile if the tube and shell side coefficients are 3ht, and 3 hs, respectively. a) Draw the temperature profile for this heat exchanger. b) Draw the temperature profile if the tube and shell side coefficients are 3ht, and 3hs, respectively. c) Would the exit temperatures change? If yes, how? Explain the reason of your answer. d) Write down five different modifications that can be done to increase ht and hs if the mass flow rate fed to tubes and shell is constant? Explain them briefly. Solve all of the parts I will give thumbs up
