Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

- 2.1.What advantage does the effectiveness-NTU method have over the LMTD method?DISCUSSION: 1-why do different materials have different specific heat 2-which materials more effective in heat exchangers ,the less specific heat or the greater one. 3-discuss the sources of error in the experiment ,and how could we minimized it .Point out the similarities and differences between the pressurized water reactor (PWR) and the boiling water reactor (BVR) . Analyze the advantages and disadvantages of selecting Gas coolant over Liquid-Metal coolant in fast breeder reactor (FBR)
- Oxy-acetylene torches can be used to cut or weld metal .Oxygen and acetylene are fed from separate compressed gas cylinders through pressure regulators to the torch where they are mixed and combusted .To estimate the amount of metal that can be cut or welded per unit volume of gas, the composition of the gases produced by combustion and heat produced by the combustion reaction must be determined .For this problem: Define a closed system that can be used to calculate the heat produced Define an open system that can be used to calculate the heat produced List at least two intensive variables that are important in calculation List at least two extensive variables that are important in the calculationDetailed explanation: Two AES exchangers in series have trouble heating up a process stream from 50ᵒC to 90ᵒC, and cooling down a hot stream with the same flow rate from 110ᵒC to 70ᵒC. Luckily, there is an abandoned AES exchanger available that has four times the surface of the two existing exchangers, and even better, it has the right material and sufficiently high design P & T, and would fit on the plot space occupied by the existing exchangers. Is replacement a good idea?(a) Discuss the principal operational features of a modern (Generation-II) power- producing nuclear reactor either of the pressurised water (PWR) or gas-cooled (AGR) type, with particular emphasis en the fuel type and fuel enrichment, the chain reaction, the neutron cycle, the choice and function of the moderating material, the origin and role of delayed neutrons, the nature and function of the control rods, and the nature and impact o: reactor poisoning. (b) Advanced Gas Cooled Reactors (AGRS) operate at higher temperature than Magnox reactors. Why does this require (i) different cladding; (ii) different form of fuel; (iii) different enrichment of fuel, than a Magnox reactor? (c) A fission reactor produces 3 x 10°W of electrical power. Assuming that the steam generator has an efficiency of 30%, cal:ulate the mass of 23U consumed by the reactor in one day. You may assume that the fission of one 23"U nucleus releases, on average, 200 MeV of thermal energy.

Triangular fins.Show all elements of your design including an explanation of assumptions made and justify your design decisions for the problem: When heating up a cold stream (5000 kg/h water) from 40ᵒC to 90ᵒC while cooling down a hot stream (5000 kg/h water) from 110ᵒC to 60ᵒC in AES exchangers, how many shells do you need?The thermal conductivity of aluminum is higher than that of concrete material (one of most popular building materials). Select one: O True O False An example of convective heat transfer is freezing of the ground during the winter. Select one: O True O False Fouling on heat exchanger tubes has no effect on heat exchanger's performances.
