having him around; having to deal with his alcohol and drug addictions, and deal with these ignorant females he was messing with who had nothing better to do with their time but look my info up in the phonebook, and call me. It was like a breath of fresh air when he left. I took this time that TJ was gone to emotionally and psychologically prepare as much as I possibly could for the day of my birth. On November 3rd, I went to my doctor’s appointment. I was a week over due, so the doctor was talking about inducing labor. I asked her if there was any way around doing this. She said let’s do an ultrasound and check your amniotic fluid first. I was a little hesitant, but I agreed to this. She asked do you want to find out what you’re having if we can tell? I said sure might as well. When she performed the ultrasound, she said I didn’t have much amniotic fluid surrounding the baby. Because of this, she said it was best to induce me. Afterwards, she attempted to see if she could find out the sex of the baby. The doctor said it was hard to see because the baby was hiding its genital area. She then said “I’m going to try to get the baby to move and see if we can find out”, and as soon as she said that, her ultrasound machine froze up…
syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley packed the particles in a substance are while viscosity is the resistance that a fluid has to flowing and movement. Viscosity is due to the movement of particles. The particle theory is a great tool to help us understand how…
Blood Flow as a Casson Fluid 1 THE PROBELM This problem was chosen from Problems for Biomedical Fluid Mechanics and Transport Phenomena section 8, because of my interest in biomedical engineering. How the body works on the most fundamental chemical and physical levels is something that has always fascinated me. This problem, and others in the section on blood flow, offered me a chance to delve deeper into how the body works as well as transport phenomena. The problem gave us a solved velocity…
Objectives With the use of similar apparatus equipment through constant temperature at atmospheric pressure, the viscosity will be determined by tests in two different fluids in sets of two ball trials; along with data collected from a third set. By reducing errors and obstructions it will justify data for better discuss and calculated results, supporting the theory beyond the lab report to resonate in helping others comprehend the experiment. Procedure The experiment was…
The experiment of fluidization in packed column was determined by using air as the conveying media. The fluidized bed is when the air make the solid to behave like a fluid. For this experiment, two columns are use which one column are filled with sand and the other one filled with aluminum oxide. The bed height of aluminum oxide is 100 mm and have a particle size about 250 micron (mesh 60). The minimum fluidization velocity is used to determine the pressure drop. As mentioned above, when the…
Computational Fluid Dynamics Computational fluid dynamics (CFD) is the simulation of fluids in engineering systems using modeling such as mathematical physical problem formulation and numerical methods like discretization methods, solver, numerical parameters and grid generation. Computational fluid dynamics is based on the concept of Reynolds averaging of the unsteady Navier-Stokes equation commonly known as (RANS) which are considered by Leishman to be the most adaptable method for…
Fluid dynamics and Bernoulli's equation Moving fluids Fluid dynamics is the study of how fluids behave when they're in motion. This can get very complicated, so we'll focus on one simple case, but we should briefly mention the different categories of fluid flow. Fluids can flow steadily, or be turbulent. In steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented…
Friction loss is defined as the pressure loss or head loss that usually occurs in pipeline fluid flow because of the viscosity effect near the surface of the pipe. When the fluid flows along the pipeline, it produces frictional resistance thus results in loss of energy or total head loss of the fluid. Therefore, experiment was conducted to verify the Darcy Weisbach equation by determining the pressure loss along a horizontal pipe. Figure A below shows the diagram of friction loss along a…
for the restricting flow. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (either liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice. But as the fluid is forced to converge to pass through the hole, the velocity increases & the fluid pressure decreases. Orifice Plate is the heart of the Orifice Meter. It restricts the flow & develops the differential pressure which is proportional to square of…
Take for instance a red plastic cup that is full of liquid. Now consider removing a circle of plastic from the bottom of the cup with the diameter of a regular pencil. How long will it take to drain all of the water? How much liquid is falling from the cup each second? Because of the work that has been done in fluid dynamics, we have a simple formula to help us answer these questions. Q=aC2gh In which Q represents the flow rate, a represents the cross sectional area of the hole, C is a…
