i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.

CHEMICAL MATERIAL BALANCE – EXAMPLE 2.2 : Three hundred gallons of a mixture containing 75.0 wt % ethanol and 25 wt % water (mixture specific gravity = 0.877) and a quantity of a 40.0 wt % ethanol - 60 wt % water mixture (specific gravity = 0.952) are blended to produce a mixture containing 60.0 wt % ethanol. The specific gravity of a substance is the ratio of density of a substance compared to the density of water. The symbol of weight percent is wt %. (a) Estimate the specific gravity of the 60 % mixture by assuming that y = mx c where y is wt % ethanol, x is mixture specific gravity. Values for m and c are constants. (b) Determine the required volume of the 40 % mixture.

A liquid with 60 mole % component 1 and 40 mole % component 2 is flashed to 1210 kPa. The saturation pressure for component 1 is ln (PSAT) = 15 - 3010 / (T + 250) and for component 2 is ln (PSAT) = 14 - 2700 / (T + 205) where PSAT is in kPa and T is in degree Celsius. By assuming the liquid is ideal, calculate (a) the fraction of the effluent that is liquid; (b) the compositions of the liquid and vapor phases. The outlet T is 150 degree Celsius.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.2 : Calculate the cooling duty, H required to condense and cool acetone from 100 degree Celsius to 25 degree Celsius at atmospheric pressure. The heat of vaporization for acetone at its normal boiling point is 30.2 kJ / mol. The boiling point of acetone at atmospheric pressure is 56 degree Celsius. The flowrate of acetone through the condenser is 100 mol / s = N. Value of sensible heat needed to increase the temperature of acetone in liquid form from 25 to 56 degree Celsius is 4.06 kJ / mol. Value of sensible heat needed to increase the temperature of acetone in vapor form from 56 to 100 degree Celsius is 3.82 kJ / mol. Unit of H is kJ / s.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.3 : For liquid benzene, the CP constants are : a = 129440, b = - 169.5, c = 0.64781. Reference temperature is 298 K. The temperature of benzene is 60 degree Celsius. Calculate the enthalpy of benzene by using the formula H = a (DT) + (b/2) (T^2 - TREF^2) + (c/3) (T^3 - TREF^3) where ^ is power, DT is temperature difference with TREF = 298 K. H is in J / kmol.

Process of resolving a specific problem Problem helps to enhance your ability to live life happily. Yes, it looks stupid when somebody say something like this. But it is true. If you say, “how?” I explain how. When there is a problem in ones life, he tries to solve it. Once he solves the problem the satisfaction of solving the problem which he feels has no words. You can see it in his eyes, on his face, in his footsteps, and not the least all around where he is. So tell me, it works? So never give up in your life. Live the life with problem, because life’s other name is problem. No one on the earth saying he or she has no problem. One who does not say that I have problem but try hard to solve the problem is the person who live life happily. There are two system of solving the particular problems. One is: solve intuitively. Two is: solve systematically. From my point of view, solving the problem systematically is much easier, more balanced and logical. To solve the problem systematically there are some instruction like relaxing head for some time, think on problem and the solution. One must not mix two things together in such a way that you can not differentiate them. If essential, there should be different solutions for different problems. In solve problem systematically, one come across five types of questions or we can view it as steps to solve the problem. They are: 1 What are the sources of problem is means “establish the goal”: “To live is to have problems and to solve problems is to grow intellectually.” (J. P. Guilford) No problem exists in the absence of an objective. We need to know exactly what and where we want to arrive at in order for us to properly determine our track and direction. Knowing our direction is an important aspect in problem solving, as what Diana Ross said, “Do you know where you’re going to?” 2 What the problem is exactly means “identify and define the problem”: “Microsoft is company that manages imagination” (Bill Gates). It is definitely related to imagination i.e. asking ourselves what is the problem and to seek to understand more why we think there is the problem is recognized what caused it in order for us to get an objective. 3 What are the solutions of problem means “set your priorities”: “The best way to get a good idea is to get a lot of ideas” (Linus Pauling) Bifurcation between which solutions are “must” and which are “want” is difficult task. The solution which must be taken to solve the problem is listed out. Therefore it is said that “the only joy in the world is to begin.” (Cesare Pavese). 4. Which solution is best among all means “brainstorm for solution”: “That human mind is like a parachute – it functions better when it is open.” (Cole’s Rules) As per this narration, I can say that brainstorm for the solution to the problem is must. When you ask for the opinion of other, you can decide upon what to do and don’t. 5. What action to be taken to solve the problem means “plan your course of action”: “It is not enough to just do your best or work hard. You must know what to work on” (W. Edwards Deming). Plan your course of action with regard to the resources needed to implement the solution. In Living a Life That Matters, Harold S. Kushner (the Massachusetts rabbi whose best selling books include When Bad Things Happen to Good People) suggests that the most successful lives are the ones that most effectively manage and resolve that problem. In a nutshell, to solve the particular problem, Rene Descartes says that “It is not enough to have a good mind; the main thing is to use it well.” FIND OUT GRAMMATICAL ERROR?
