Answer the following problems in detail.
problem 1) prepare down applications of heat exchangers and describe why is counter flow HX better than parallel-flow HX?
problem 2) describe overall heat transfer coefficient? Derive the expression for overall heat transfer for a tubular heat exchanger (HX) based on inner surface area.
problem 3) Sketch temperature profile for parallel and counter flow type heat exchangers.
problem 4) prepare down the selection criteria for the heat exchangers?
problem 5) describe boiling in detail? Which mechanism is responsible for very high heat transfer coefficient in nucleate boiling?
problem 6) A brief note on multiple effect evaporators
problem 7) Sketch the neat and clean diagrams for plate heat exchangers and plate fine heat exchangers.
problem 8) Sketch a schematic diagram for Heat Pipe and describe its working in detail.
problem 9) What do you mean by fouling factor? What is its function in the heat transfer process?
problem 10) prepare down the compact heat exchangers and their area of applications?
