You are required to design a jacketed system to heat a continuous flow of 1m³/min of a liquid with the physical properties of water from 20◦C to 80◦C. You may assume that the heating medium is condensing steam, so that the jacket temperature is always at 100◦C. You decide to use a cylindrical tank with a length-to-diameter ratio of 1, and you may assume that that h_T = 800 W/m2 K. How large must the tank be?
