Bulk Grain Cargo Process of cleaning holds 1.Hold Cleaning – it can be done by a shovel or a swept clean. The stevedores at the discharge port should swept the holds before completion of the discharge to minimize the remaining residues. Hold Cleaning 2.Hold Washing Down – once sweeping and cargo residues are removed‚ the next task is to wash down the hatch cover and holds with saltwater. Hold Washing down 3.Use of chemicals - the use of prewash is to protect the paint coating of holds

calibrated by just weighing the water they deliver. As for volumetric flask‚ the weight of an empty flask is recorded. Next‚ weigh the flask after filling it with water to the mark. After that‚ it is crucial to convert the mass to volume. The water density at a temperature will aid this process. The compliance of the Volume Occupied by 1.000g of Water Weigh in Air table is deemed necessary throughout the comparison. In order to obtain the true volume of volumetric glassware holds‚ this formula will

causes osteoporosis? In childhood‚ bones grow and repair very quickly‚ but this process slows as you get older. Bones stop growing in length between the ages of 16 and 18‚ but continue to increase in density until you are in your late 20s. From about the age of 35‚ you gradually lose bone density. This is a normal part of ageing‚ but for some people it can lead to osteoporosis and an increased risk of fractures. Other things that increase the risk of developing osteoporosis include: diseases of

the material. In general neither of these two properties are true for rocks. 10. Some Relationships Between the Elastic Constants G= E 2(1 + ν ) λ= Eν (1 + ν )(1 − 2ν ) K= E 3(1 − 2ν ) Where λ = Lame’s constant and K = bulk modulus. Note: The five elastic constants listed above (E‚ν‚G‚λ‚K) are the most common for reasons that will be shown. However‚ there are only two independent elastic constants for isotropic conditions and Hooke’s law can be written with any two

Dairy Farming 1. Introduction Dairying is an important source of subsidiary income to small/marginal farmers and agricultural labourers. The manure from animals provides a good source of organic matter for improving soil fertility and crop yields. The gobar gas from the dung is used as fuel for domestic purposes as also for running engines for drawing water from well. The surplus fodder and agricultural by-products are gainfully utilised for feeding the animals. Almost all draught power for

Unit Weight is influence by gravity forces while mass isn’t (Unit Weight=Weight/ Volume while Density= Mass/Volume)- Weight = Mass x Gravity acceleration So we can use the similar equations on related calculation if there is only density Specific Gravity Specific gravity can be determined as a ratio
