Pressure gradient is the flow rate of a liquid through a pipe. This is directly proportional to the difference between the pressures at the two ends of the pipe and inversely proportional to the pip's resistance. The pressure gradient is directly dependent upon blood vessel radius which essentially controls blood flow. The bigger the blood vessel radius, the more blood flow or fluid flow. The smaller blood vessel radius, the lesson blood or fluid flow.

Another assumption we used was amid the calculation of the current pipeline amongst D and E. It was demonstrated that there was a prerequisite to convey an extra stream, and accordingly a new pipeline (looped) was required. A diameter was to be assumed for the new parallel pipeline. After two unsuccessful attempts with diameters of 0.3 m and 0.35 m, our third diameter of 0.38 m, successfully carried the additional flow rate of

We set up 3 fermentation set-ups, labeling them 1, 2, and 3. Then, filled a tub with hot water and inserted the end of the plastic tubing into one of the test tubes and submerged the collection tube and plastic tubing in the tub. After that, we mixed the fermentation solutions for the other tubes, (tube 1 got 4mL of water and 3mL of corn syrup, tube 2 got 3 mL of water, 1 mL of yeast and 3 mL corn syrup, tube 3 got 1 mL water, 3 mL yeast and 3 mL of corn syrup) . We then mixed each test tube and put the rubber stoppers in the fermentation tubes. Finally, we marked the water level on each collection tube with a wax pencil to use as the baseline. Then at 5 minute intervals we measured the distance from the baseline for 20 minutes.

where A2 is the cross-sectional area of the throat, C is the coefficient of discharge (dimensionless), gc is the dimensional constant, Q is the volumetric rate of discharge measured at upstream pressure and temperature, w is the weight rate of discharge, p1 and p2 are the pressures at upstream and downstream static pressure taps, respectively, Y is a dimensionless expansion factor, β is the ratio of the throat diameter to pipe

Alternatively, it can also be explained by referring to the equation , where the k value is constant while the hydraulic gradient i defined by i = ΔH/L increases because the head difference ΔH is constant while the flow length L becomes shorter when it gets closer to the barrier wall.

A volumetric pipette & measuring cylinder can be calibrated by just weighing the water they deliver. As for volumetric flask, the weight of an empty flask is recorded. Next, weigh the flask after filling it with water to the mark.

During the working of the hydraulic system, it was observed that the pressure in the system was found to be in “between 1,500 to 2,000 psi” (para.3) instead of 3,000 according to the catalog. To overcome this situation, shaft seal kits were ordered, but it did not manage to overcome the failure.

Abstract- A numerical investigation has been carried out for incompressible turbulent flow through 900bend pipes. The model is based on the numerical solution of conservation equations of mass and momentum. The results of the simulations of the flow in the form of contour and vector plots for two types of pipe bend both mitre and smooth bend with seven different Reynolds numbers (2.0+E04, 2.5+E04, 3.0+E04, 3.5+E04, 4.0+E04, 4.5+E04 and 5.0+ E04) are presented in this paper. From the obtained results, it is seen that the mitre bend produces more turbulent kinetic energy, eddy viscosity, skin friction factor compared to the smooth bend. To put an emphasis on the smooth bend for different R/D ratios, the static pressure distribution along the inner, outer wall and the pressure loss factor with different Re numbers are analyzed. However, it is noticed that as Re increases the pressure gradient changes rapidly at the inner and the outer wall of the bend. Again, the total pressure loss factor k increases as the R/D ratio decreases and due to higher velocity heads factor k decreases as Re increases. The numerical results are found to be in a good agreement with experimental

Among those courses, I found the hydraulic ones quite interesting, especially designing different hydraulic structures for various water engineering purposes. Thereafter, hydraulics has become my all-time impressing subject. In fact, its attractiveness motivated me very much to become among the three top students in related courses. Apart from hydraulics theories, I enjoyed the practical courses very much especially my internship in a laboratory where I cooperated a PhD student to conduct experiments on the hydraulic jump over a rough bed. This event ignited my desire for doing my own research and advancing my education to the next level. Therefore, I took the Iranian National Entrance Competition for Master Programs and gained the rank of 23 out of 1710 rivals for Agricultural Engineering-Hydraulic Structures program in 2008. I spent a whole year studying intensively for this competitive exam; however, my enthusiasm helped me win a place with a very good
