3.3 Tribological properties of Cr-B-C-N coatings in artificial seawater Fig.10 shows the friction behaviors and the mean-steady friction coefficients of Cr-B-C-N coatings sliding against SiC balls in artificial seawater. As seen in Fig.10a, it is clear that the CrCN coatings showed higher friction coefficient than other coatings during the tribo-test in artificial seawater. The initial friction coefficient of CrCN coatings was 0.17, while that of CrBCN coatings ranged between 0.14 and 0.15. For…

A water jet cutter, commonly called a water jet, is a tool that uses a very high-pressure jet of water or a mixture of water and an abrasive to cut a wide variety of materials. A water jet that does not use abrasives is referred to as a pure water jet or water-only cutting [1]. For a pure water jet (Figure 1) the water is pressurized to the range of 20 - 94 ksi, 138 - 649 MPa at the inlet and forced through an orifice with a diameter of between 0.25 - 4 mm creating a very thin high velocity…

Thermoelasticity describes the interaction of the mechanical fields such as stress, strain and displacement with temperature field and investigates the interaction on the basis of the thermodynamics of the irreversible processes. It relates two separate and independently developed sciences: the theory of elasticity and the theory of heat conduction. The two basic branches of elasticity, namely elastostatic and elastodynamics are developed under different thermodynamic assumptions. The problems…

1) What differential diagnoses should be considered for this individual? When addressing this question, the provider may feel overwhelmed with volume and possibility. Consequently, a thorough knowledge of disease pathology, presentation, and an understanding of the establishment and ranking of the most likely differential diagnoses is of immense importance. Like with any presenting complaint, the history and physical should serve as the guidepost for the differential diagnosis. Every disease…

voids are filled with a fluid (usually air). The physical properties of the materials can be characterised by bulk, macroscopic and microscopic properties. Most of which have an impact on the acoustical performance of the material. Sound energy is lost in porous materials when it is transformed into heat. This is caused by a combination of effects. Firstly, there are losses through the viscous effects between the solid matrix and the fluid when pressure waves causes the fluid to move…

Viscosity and Flow Rate by Hasnain S. and Vinh T. What is Viscosity: Viscosity is the measurement of how fast a fluid will flow. In other words, it is the “thickness” or “thinness” of a fluid. The internal friction or resistance it has as well as the temperature in which the fluid is at determines the viscosity of the substance as well. If there is more internal resistance or friction, then the particles of the substance won’t slid past each other as easily and therefore make the substance…

This power and time is chosen to allow for any possible heat transfer to be observed. If the time is too short no heat transfer will occur and if the power is too low the ablation zone will be so small that the fluid flow will be too far from the zone too observe any sort of impact from the fluid flow. FLOW VESSEL…

I. Summary A. Why we exist 1. The Harris County Permit Office began issuing development permits in 1973. 2. Permits are issued in accordance with Harris County regulations to ensure that unincorporated areas of Harris County are able to qualify for flood insurance through the National Flood Insurance Program. 3. The residential department is diligently working to minimize the loss of life and property from high water events (i.e. Floods, Tropical Systems, and etc.) 4. The importance of flood…

The gear ratios used for this transmission were 2.52 for 1st gear, 1.52 for 2nd gear, and 1.0 for 3rd gear. known as a “delayed engagement.” This issue is simply the result of a low fluid level or a clogged filter/screen. He went on to say that if a TH350 suffers from this “aging complaint” only when cold, it’s most likely that the lip seals have become too brittle. If this is the case, then they are not properly sealing until after…

Does the number of tiny holes in the parachute affect its descension rate Introduction This experiment will determine if the number of tiny holes in the parachute effect will its descension rate.This science of this project includes newtons second law, drag force, gravity, velocity and terminal velocity . This experiments main focus is air resistance. Project rationale/ purpose In this experiment I will test if having small holes in a parachute help the parachute from falling as fast. This…
