SECTION 50 FORMAT AND CONTENT OF THE LAB REPORT All reports in the Mechanical Engineering Laboratory This information is necessary in order that the report require a formal laboratory report unl specified oth- erwise. The report should be written in such a that anyone can duplicate the experiment and obtain the same results as the originator. The reports should can be properly filed and the grade recorded. INTRODUCTION be simple and clearly written. Reports are due one Thlis section tells the reader what the experiment is week after the experiment was performed, unless spec about. It begins with a description of the problem that is being investigated. It includes the background and provides the reader with a clear concise statement The report should communicate severad ideas to the explaining the purpose of the experiment. This is one of the laboratory report experimenter is in effect trying to convince the reader that the experiment was performed in a straightfor how relate to the stated object because everything included in the report to detail. A poorly written report might instead lead THEORY AND ANALYSIS the reader to think that just as little care went into performing the experiment. Second, the report should be wel organized.

Each symbol in the page for each lab report. Information on the title page equations should be named and its dimensional unit given. An example, Newtons Second Law of Motion can be written as where F is the unbalanced external force in N, m is the mass of the block in kg, and a is the acceleration These features are very important in report writing. It is these features that will make a well done technical report appear professional in every way Course (ENGR 3443) PROCEDURE Partners: Names of Lab Partners Instructor: Name of Lab Instructor Date the Experiment was Performed Due date for this Report This section describes the equipment used in the ex- periment and the test procedures.

Explanation / Answer

INTRODUCTION:-

Shell and tube heat exchangers are used widely in many different chemical processes because of their numerous advantages. Shell and tube heat exchangers are capable of having a large surface area for heat transfer to take place. This is because of their numerous tubes. This design also minimizes the necessary overall length. Shell and tube heat exchangers also offer a lot of versatility when it comes to operating pressure and temperature. Since there are limited pressure and temperature restrictions, small shell and tube heat exchangers can accommodate a higher heat duty. This is because additions can be made to neglect thermal expansion effects as well as variations to the thickness of the exchanger.

Theory and Analysis:-

The equation used to determine this energy is

  Q=MCpT

  M is the mass flow rate of the water, and is a measure of the flow of water into the system. In order for proper calculations, data must be collected when the system is at steady state. Cp is the specific heat capacity of the material, which is the amount of energy per unit mass required to raise the temperature of a substance by one degree. T is the change in temperature of the fluid throughout the system.

  To determine the efficiency of the unit, the equation

    Qhot= Qcold + Qloss

  Another calculation used when analyzing heat exchange is calculating heat transfer between two elements. The equation used is

Q = UATlmF

  U is the overall heat transfer coefficient.

For counter flow heat exchanger LMTD IS

  (T2-T1)/ln(T2/T1)

  where T1 and T2 are

  T2 = T(hot, in) - T(cold,out)

  T1 = T(hot,out) - T(cold,IN)

  Procedure:-

To begin experimentation with the small shell and tube heat exchanger, the proper apparatus was set up in accordance with the LabVIEW software provided. First, the chiller was set at 20 degrees Celsius and power to all components on the heat exchanger panel were turned on. To complete the first technical objective, the tube-side flow was varied. Initially, the tube-side valve was set at 10% open and the shell-side valve was set at 50% open. After allowing the outlet temperatures of both the tube and shell-sides to stabilize and reach steady state, the tube-side valve setting was varied, allowing it to reach steady state again. Steady state was achieved when the data plots showed that the temperatures of the corresponding data plots were level and ceased to change. This was repeated two more times and the valve settings and temperature data are summarized in Table 1. To evaluate technical objective two, the shell and tube valves were initially set again. However, this time, the shell-side flow rate was varied.

Result:-

so you have the result table, so using that explain the result and find the required thing,.

and at last explain that result as the conclusion
