Condensers are involved within systems in order to cool an environment with the evaporation and condensation of a fluid. LO3.1: Lesson . 1. : . . Type of Heat Exchangers (. Recuperators. ). Aim. LO3: To be able to Evaluate Heat Transfer Equipment.. Learning Outcomes. At the end of this session the students will be able to…. Group 5. Maha El-Deeb. Khashayar Moez. William Read. Michael Teklu. T. ypical . uses for heat exchangers . Heat a fluid before a process unit such as a reactor or a distillation column. Remove heat from a process to keep the temperature at a desirable level. DESCRIBE the process that occurs in the following regions of the boiling heat transfer curve:. a. Nucleate boiling. b. Partial film boiling. c. Film boiling. d. Departure from nucleate boiling (DNB). How does heat energy get from the Sun to the Earth?. There are no particles between the Sun and the Earth so it CANNOT travel by conduction or by convection. . ?. RADIATION. How can we relate our new understanding to the greenhouse effect?. USING THERMAL ENERGY. Thermal Energy. Lesso. n Objectives:. • Explain the relationship between temperature and thermal energy.. • Define heat and specific heat.. Thermal Energy. Lesson Summary:. Heat is the transfer of thermal energy between objects that have different temperatures. . “L JJAM” aka “Dream Team” aka Team 3. CHBE446 02/02/18. HOT HOT HOT! . Background Theory. Conduction.
