Cargo Handling Safety 1. Why cargo gear should be inspected visually before the start of cargo operation? All cargo handling gears should be inspected before the cargo operation is commenced to ensure that all gears are in good working condition in order to prevent any accident and/or damage to cargo‚ ship‚ and/or injuries and loss of human lives. 2. Why SWL of equipment should never be exceeded? Safe Working Load (SWL) is the allowable load of block‚ wires‚ ropes‚ derrick booms‚ crane jibs‚ hooks

Through this lab‚ I will learn how the changes in temperature can cause condensation to occur and how it affects relative humidity. Before completing this lab‚ one must understand that “all air has some moisture in it‚ but how wet the air feels depends not just on the amount of moisture but also the temperature of the air” (Lab Intro Given). In the meteorology career‚ terms such as “dew point and “relative

In this document‚ I jotted down some notes while putting together the reading material. These notes point out some of the reading content to pay particular attention to. The notes are divided into section headings based on the reading material. This is not meant to be a complete list of everything that you need to know from the reading Water in Atmosphere You should know what is meant by phases of water and phase changes of water. Water vapor is extremely important in the atmosphere for many reasons

Abstract The phenomenon of evaporative cooling is a common process in nature‚ whose applications for cooling air are being used since the ancient years. In fact‚ it meets this objective with a low energy consumption‚ being compared to the primary energy consumption of other alternatives for cooling‚ as it is simply based in the phenomenon of reducing the air temperature by evaporating water on it. This process can be an interesting alternative to conventional systems in these applications where

Climates and Oceans- 1. With coastal climates‚ the locations are on the windward side‚ meaning the weather patterns move from the ocean to land‚ giving them mild summers and cool winters. This means that there isn’t a very large temperature range for coastal climates. Inland climates are more of the land heating and cooling‚ because they heat to high temperatures in the day and then cool a great amount at night. Also‚ the weather patterns are moving from land to water‚ creating warmer summers and

Mt. Adiabatic Let’s look more closely at how the air changes temperature when it rises or drops. We know that warm air rises‚ and when it rises it becomes cooler. If you remember that‚ you can reason your way through a lot of meteorology. Adiabatic heating and cooling implies a change in temperature of the parcel of air without gain or loss of heat from outside the air parcel. Adiabatic processes are very important in the atmosphere‚ and adiabatic cooling of rising air is the dominant cause of cloud
