you have develope a super heat sotrage fluid and now need to determine its heat of vapoirization you set up an experiment with 60m cylindrical copper tube. the fluid enters the tube at 130 C at 100% vapor and exits at saturated liquid. the outer surface is exposed to water at 25C with a heat transfer coefficient of 200 W/m^2k. The inner surface heat transfer coerfficent is 350 W/m^2k. The inner tube diameter is 20 cm and the tubing is 2cm thick. If the mass flow rate is 0.1 kg/s. what us the heat of vaporization.
