Guess what happened? We got our tails burned every time from the heat, steam, and black nasty garbage dropping down on us. The protective cone of water works great IF you are not in a confined super heated atmosphere. Like for approaching a gas meter fire, or a car fire where the heat can dissipate into the atmosphere. I think the best choice is having both types of nozzles available and selecting the right one for the job. Either way, a smooth bore stream or a straight stream from a combination nozzle is the best choice for interior work.

Emmanuel and his mother live in an urban community-housing complex. The building is worn down and dirty from the urban dust, cockroaches, and mold. Emmanuel is five years of age and has suffered from asthma for the last two years. One evening, his mother poured him some milk and put him to bed. Shortly afterward, Emmanuel woke up wheezing and coughing. As he gasped for air, he became more and more anxious. His mother ran for his inhaler, but he was too upset and restless to use it. Emmanuel’s skin became moist with sweat, and as he began to tire, his wheezing became quieter. His mother called 911 and waited anxiously for the ambulance to arrive.

In early May 2008, talk began between president of Flinder Valves, Bill Flinder and Tom Eliot, chairman and CEO of RSE about a possible acquisition of Flinder Valves by RSE. The industrial manufacturing industry had taken a hit due to rough economic times and the acquisition made sense. Both leaders were very concerned about the challenges and risks of the deal. Flinder was a company that engineered and manufactured specialty valves and heat exchangers. These products required extensive research and development and they were one of very few firms working in these types of applications. A bullk to FVC’s sales came from defense and aerospace applications. They were known for their

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

Questions 1, a and b answers: As we know (also shown in Figure 1 of this paper), the mixing vanes in the fuel assembly are not symmetric and the flow pattern might not be periodic or cyclic, so it is impossible or extremely difficult to extract information out of any “free boundary” 1x2 section from experimental data taken under the 5x5 bundle test geometry and use this information to benchmark CFD modeling of a 1x2 channel without any convincing justification of how the boundary (or missing boundary) effect is handled. The challenge is how to apply the data obtained within a 5x5 assembly without a 1x2 confined flow boundary to

5.Position gas collecting hose so it runs from reaction vessel through gas collecting box to opening of the graduated cylinder. The idea is that any gas coming through the tube will rise in the graduated cylinder and displace the water in it.

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

In this experiment, the velocity profile for a flat plate at zero pressure gradient of a boundary layer at two different stream wise points were acquired. The investigation was also based on and how changes in Reynolds number affect the velocity distribution within boundary layers. Parameters such as the Momentum Thickness, Displacement Thickness, Shape Factor, shear stress and coefficient of friction was also calculated to gain a better understand of boundary layers. The experimental values calculated were compared to the theoretical Blasius for laminar flow and Power Law Solutions for turbulent flow to see how they varied. It was found out the higher the Reynolds number the greater the boundary layer thickness. As the

Assuming no viscous forces present an inviscid model has been used for the calculations. Also from the equation of the Reynolds number Re=ρvl/μ due to Re being really big rearranging and assuming v and l to be constant the viscous force μ =ρvl/Re becomes negligible.

Both the orifice and the Venturi meters produce a restriction in the flow and measure the pressure drop across the meter. The velocity of a fluid is expected to increase as the fluid flows from an open area, to a more constricted area. Assuming incompressible flow, a negligible height change, and steady state, Bernoulli’s equation can be simplified to show the correlation between the volumetric flow rate and the pressure drop. The equation for both meters is as follows:

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.

This report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it. This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. The experimental lift force the aerofoil experienced when positioned at different angles of attack was then compared with theoretical values. An attempt was made to explain any discrepancies between experimental and theoretical values.

To look at how the pressure drop changes when the average velocity is altered in a circular pipe and to plot a graph of Friction Factor versus Reynolds

The lid-driven cavity flow is most probably one of the most studied fluid problems in the
