Laboratory #2 Technical Report

Ill send the filled out work sheet

Overview

Your individual Technical Report should address the objectives of Laboratory #2. It should presentthe data collected and calculated and provide an interpretation of the results.Your analysis should focus on the comparison between the experimental values of friction factor andthe corresponding theoretical predictions (also represented graphically in the Moody Chart) for thelaminar, transitional and turbulent flow regimes this type of approach is often used to experimentallyvalidate modelling techniques.In this exercise, you should demonstrate your analytical and communication skills with a clear andsuccinct presentation of technical content to disseminate engineering knowledge.

Assessment

The Technical Report is worth 50% of the Laboratory Portfolio.

Please refer to the rubric in the Assessment and Feedback Specification available on BlackBoard forthe expectations, the Engineers Australia Stage 1 competencies to be demonstrated and the criteriaused for marking Technical Reports.

Figure presentation

These guidelines must be followed when preparing the two required graphs:
Figures should be large enough and of sufficient resolution for details to be discernible.
Anytext within the figures should be large enough to be legible.
Figures should have a caption including a relevant description.
Axes should be labelled appropriately.
Figures should include a legend when necessary.
Figures should only include a title if it provides information not appearing anywhere else (i.e. a title

restating the caption or the axes labels is superfluous).

Data points should be represented by markers, which may be connected by a dashed or dotted line

(original data points may need to be reordered to avoid the line to cross itself).

Data-fitting curves should only be included if they provide relevant information that can be used to

support discussion points.

For the graph showing the pressure gradient against the mean velocity of the flow:

Data points should be plotted as three different sets corresponding to the three flow regimes.
Alinear scale should be used for both axes.

For the graph showing the friction factor against the Reynolds number:

Datapoints should be plotted as three different sets corresponding to the experimental data, laminar

predictions and turbulent predictions.

Alogscale should be used for both axes.
the regions corresponding to the three flow regimes should be indicated in the graphFormatting and Structure

The Technical Report must be prepared using the template available on BlackBoard and must

include the following sections:

Experimental Data: Report in the table the experimental data collected during Laboratory#2 session.

Calculated Data: Report in the table the processed data and corresponding predictions. Additional

data (e.g. relative error) may be included in this table to support discussion points in the Analysis

and Interpretation section.

Sample Calculations: Provide the steps showing how the processed data and corresponding predictions were obtained for one of the water manometer tests corresponding to the laminar flow regime; an one of the mercury manometer tests corresponding to the turbulent flow regime.

Graphs: Provide the two required graphs pressure gradient against mean velocity of the flow; and friction factor against Reynolds number.

Analysis and Interpretation: For each subsection, address the following points (200~250 words for

each subsection):

Experimental data: Describe and comment on the variations of pressure gradient with flow velocity and on the variations of experimental friction factor with Reynolds number for the different flow regimes. Compare and comment on the trends in the two graphs (dimensional and non-dimensional).

Experimental validation: Comparetheexperimentalvaluesoffrictionfactorandthecorrespond ing theoretical predictions for the different flow regimes. Comment on the agreement between experimental and theoretical values, and discuss possible discrepancies.

Describe possible

sources of errors and propose alternatives that may improve the quality of the measurements.

Critical reflection: Provide a brief critical analysis of the work conducted and how the objectives

were addressed. Comment on the outcomes of the study and their significance in a broader

context.
