Dec 16,2013·Calculation of secondary containment capacity,based on a design criterion of 110% of tank storage capacity Containment surface area = 45 ft x 20 ft = 900 ft.2.Tank volume,based on 100% of tank capacity = 20,000 gallons Tank volume,in cubic feet = 20,000 gallons / 7.48 gallons/ft. How much moisture is in oil in a transformer?How much moisture is in oil in a transformer?If one-half percent of this weight is moisture,and if completely in the oil,it would be just over 5 pounds of water dissolved in 1,000 gallons (7,500 pounds) of oil.This would mean a perfectly dry transformer would have 780 ppm of moisture in the oil!Moisture in Transformer Insulation How much water is in a paper transformer?How much water is in a paper transformer?An interesting way to show this involves considering a 1,000-gallon transformer with an estimated 1,100 or so pounds of porous/paper insulation.If one-half percent of this weight is moisture,and if completely in the oil,it would be just over 5 pounds of water dissolved in 1,000 gallons (7,500 pounds) of oil.Moisture in Transformer Insulation

A dozen ways to measure fluid level and how they work - ABB

A buoyant force equal to this displaced volume multiplied by the process fluid density pushes upward on the displacer,reducing the force needed to support it against the pull of gravity.The transducer,which is linked to the transmitter,monitors and relates this change in force to level.A bubbler-type level sensor is shown in Figure 3.A dozen ways to measure fluid level and how they work - ABBA dozen ways to measure fluid level .The demands of sophisticated automated processing systems,the need for ever-tighter process control,and an increasingly stringent regulatory environment drive process engineers to seek more precise and reliable level measurement systems.Accurate Location of Transformer Hottest Spot by FEMVolume 37 No.6,January 2012 36 Accurate Location of Transformer Hottest Spot by FEM and Thermal Models Dr.V.Rajini SSN College of Engg India ABSTRACT The formation of hotspots in the power transformers is one of the major threats for the life of the transformer.Therefore,the hot spot temperature value is an important parameter

Bunding and Spill Management Guidelines

5.4.1 Tank storages The designed net capacity of a bunded compound in a tank storage facility should be whichever is the largest of the following At least 110% of the volume of the largest storage vessel; or At least 110% of the combined volume of any inter-connected vessels within that bunded area; orBunds and secondary containment - GPT EnvironmentalUsing the 110% rule the bund would need a capacity of 11,000 litres,using the 25% rule the bund would need a capacity of 12,500 litres therefore the higher volume of 12,500 litres is necessary.Where multiple containers are being housed in the same bund it is important to ensure the contents of the tanks are compatible with one another.Calculate Secondary Containment - Expert AdviceLets say you are purchasing a PIG Custom Collapse-A-Tainer Containment System and you need 100% containment for a 520-gallon tank that has dimensions of 5.5L x 3.5W.Using the formula above,you can easily figure out the dimensions your Collapse-A-Tainer has to
