eat exchanger is any device that is used to transfer heat from one fluid to another and the two fluid must be hot and cold fluid Example :car radiator                        Direction of flow 1. Parallel flow  2. Counter flow Heat exchanger  3. Cross flow Heat exchanger                    Design of Heat exchanger   1. Concentration flow  2. Shell and tube heat exchanger  3. Compact Heat exchanger          Nature of Heat exchanger   1. Direct flow Heat exchanger  2. Indirect flow Heat exchanger  They one take in Heat is called a cold fluid and the heat carrier is called hot fluid. In hear exchanger, the temperature of each fluid changes as it passes through the heat exchanger hence the temperature of the diving wall between the fluid also changes along the length of the exchanger. Hear exchanger Design is handled by the speciality and professional. The engineers need acquittance with the heat transfer design principles to evaluate bids and to detect operating problems  Examples : Automo

 Iron is a metal which has carbon as it major continent,Steel  is the allow of carbon and Iron .                 Type of iron 1. Cast iron:  is an Iron or a ferrous alloy which has be heated to be liquefied then pour into mold to solidify. A cast iron has different types:      White cast iron      Grey cast iron      Malleable cast iron White cast iron has carbide impurities                    Production of cast iron   Cast iron is made by the melting of pig iron often along with substantial quantities of scrap steel, limestone and carbon and also taking various steps removal impurities that comes  with the Production process                      Grey cast iron It is characterizes by graphics micro structures which caused fracture of the  material to have a Grey appearance. It has lower shock resistance and tensile strength than steel .it is used for housing where the stiffness or the component is more important than it tensile strength          Example of where it is used Internal co
