Fluid Mechanics Report Instruction Water turbine is a very common used throughout the world to generate power. Although the concept of the Impact of a Jet is essentially simple‚ and it can has a highly hydraulic efficiency‚ the factor of how can produce a powerful reaction force back is also has to be considerate truly. If we can manage well‚ we can determine the best situation and the optimum deflection angle out‚ for getting the optimum force that the impact can produce. But first of all‚ we

Mechanics Revision Exercise Q1. Which of the following is/are the direct implication(s) of Newton’s first law? (1) A boy standing on a bus is ’pulled’ backwards when the bus starts moving. (2) On a smooth surface‚ when you push another person in front of you‚ you will move backwards. (3) The balls of different masses reach the ground at the same time in Galileo’s experiment (carried out on the tower of Pisa). A (1) only B (2) only C (3) only D (1) and (2) only Q2.

Introduction Soil erosion is one form of soil degradation along with soil compaction‚ low organic matter‚ loss of soil structure‚ poor internal drainage‚ salinisation‚ and soil acidity problems. These other forms of soil degradation‚ serious in themselves‚ usually contribute to accelerated soil erosion. Soil erosion is a naturally occurring process on all land. The agents of soil erosion are water and wind‚ each contributing a significant amount of soil loss each year in Ontario. Soil erosion may

EXAM 1 NOTES The actual pressure at a given position is called the absolute pressure‚ and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Most pressure-measuring devices‚ however‚ are calibrated to read zero in the atmosphere (Fig. 3–2)‚ and so they indicate the difference between the absolute pressure and the local atmospheric pressure. This difference is called the gage pressure. Pgage = Pabs - Patm The pressure at a point in a fluid has the same magnitude in all

Soil contamination Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity‚ agricultural chemicals‚ or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals. Contamination is correlated with the

Introduction Every type of soil has its own percentage of moisture content. The void in soil content water and air. The moisture content may varies for each types of soil. Different type of soil has different moisture content. Moisture content of soil also may be affected by the climate where the high humidity country tend to have higher moisture content in soil. Size or structure of the soil particles also affecting the moisture content. The properties of the soil to retain water also one of the

management can affect soil characteristics as well as soil quality. The term soil quality can be defined as the overall activity of a soil within an ecosystem that preserves biological activity and environmental quality‚ thus promoting plant and animal health (Doran et al. 1994). Alterations in soil properties and processes can affect functions that soils perform in the environment‚ which in turn influence patterns of plant growth (Ahuja 2003). Changes in land use influence several soil processes‚ such
