the range 0 – 14 bar (gauge) and to study the change in temperature of a body when being heated or cooled. Safety The apparatus is a pressure vessel. The pressure must not exceed 14 Bar (gauge)! Background 1) In order to carry out a heat transfer experiment simultaneously with measurement of vapour pressure‚ it is required that the rates of heating and cooling of the pressure vessel‚ the rate of energy addition by the heater and the ambient temperature are recorded. 2) Study the following

1.23.2 Glass types Application. This section will compare the effect of using some of the glass common types on the total cooling thermal load of the building. The cost of using these types will be studied as a comparison (effect VS Cost). 1.23.2.1 Simulation Goal The Goal of this study/simulation is to find out the relation between the Building Glass type and the total amount of the cooling load needed to keep the building temperature within the comfort zone range. The Simulation focuses on the

nductioIn heat transfer‚ conduction (or heat conduction) is the transfer of heat energy by microscopic diffusion and collisions of particles or quasi-particles within a body due to a temperature gradient. The microscopically diffusing and colliding objects include molecules‚ electrons‚ atoms‚ and phonons. They transfer microscopically disorganized kinetic and potential energy‚ which are jointly known as internal energy. Conduction takes place in all forms of ponderable matter‚ such as solids‚ liquids
