Background: As heat is a form of thermal energy‚ they tend to have the behavior of reaching a thermal equilibrium. This means that when two bodies of different temperatures come in contact with each other‚ the hotter ones will transfer heat particles to the body with a colder temperature‚ with an aim to reach this “thermal equilibrium”‚ whatever the temperature may be. The larger the surface area‚ means there can be more “paths” from the sides of the body that are capable of releasing this heat particles

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

(.)m is the mean value of ().(). The mean value of ().() can be found by means of integrals over the hemispherical sky as follows: (.)m = [0/2 ().().sin .cos .d()] / [0/2 sin .cos .d()]. For one glass cover the result is approximately (.)m = 0.70. Heat Losses The glass cover behaves nearly as a black body for long-wave radiation. We can assume that the emittance c of the glass cover is 0.95. The emittance b of the black plate for long-wave radiation depends on whether the surface is non-selective

to protect the heat exchanger. The waste gas has the following properties: Waste gas composition: Mole fraction(= 0‚9890‚ Mole fraction()=0‚0110 Temperature = 20‚00 °C Pressure = 1‚1 bar Mass flow The task is to calculate the optimal area of the heat exchanger as a function of t1. Spreadsheet calculations and Case Studies are used to show the results. A set of assumptions is made concerning: Overall heat transfer coefficient U Costs of heat exchanger related to heat exchanger area

Vocabulary: • Conduction- the passage of energy‚ particularly heat or electricity‚ through something • Rate of Change- the ratio of the difference in values of a variable during a time period to the length of that time period • Calorimeter- an apparatus for measuring the amount of heat given out or taken in during a process such as combustion or change of state. The measurements are often made by observing the amount of solid liquefied‚ or liquid vaporized‚ under set conditions. • Conservation
