Thermofluids laboratory 3

Experiment 1:
Aim:
The objective of the monometer experiment was to calculate the velocity change inside a tapered venture tube when a constant mass/volume flow rate is applied to the apparatus. In order to most accurately calculate the change in velocity, two height measurements from the monometers would have to be recorded (preferable, one located before the tube is narrowed and one at most narrow location), then applied to a manipulated Bernoulli's equation.

Apparatus:
The apparatus used during the experiment were monometer tubes positioned at various parts of the tapered venture tube. The monometer had readings of which the user could read the height the fluid reaches. The images below shows the apparatus.

Results:
The results that were recorded were the height measurements shown on the monometer. The diameters of the tubes of the monometers were also recorded. Below is a table of results.

After this part of the experiment was constructed, another set of results were obtained from the same apparatus. These results were obtained by recording the time at which dissipation of the fluid occurs over specific volumes. Table below shows the results.

56ºC for 2 hrs. The DNA was ethanol precipitated with buffer AL. The DNA was centrifuged at 8,000 rpm for 1 minute and washed with buffer AW1. The centrifugation was repeated. The samples were washed with buffer AW2 and centrifuged for 14,000 rpm for 3 minutes. The DNA was eluted from the column with buffer AE, incubated at room temperature for 1 minute, and centrifuged at 8,000 rpm for 1 minute. The column was washed with buffer AE and the process was repeated. DNA mass was determined by scanning…

Heat Transfer Lab Report

FLUIDS ABSTRACT Heat transfer by convection is extremely necessary for several industrial heating and cooling applications. The warmth convection will passively be increased by dynamic flow pure mathematics, boundary conditions or by enhancing fluid thermo physical properties. A mixture mixture of nano-sized particles in an exceedingly base fluid, referred to as nanofluids, staggeringly enhances the warmth transfer characteristics of the first fluid, and is ideally fitted to sensible applications as…
