How do you start turbine without jacking oil pump?
Jacking oill pumps are fairly new in the power industry. They are necessary today because of the large turbines with multiple low pressure shells. The longer the rotor the more likely to do damage to it as it rolls off of turning gear. The turbines containing only two low pressure wheels can be started with an auxiliary oil pump that supplies higher pressure than turning gear pumps. Most large turbines have been retrofitted with lift pumps because they prevent damage to the rotor and journals.
What process causes a material to break due to excess stress?
Either deformation in a plastic material, or fracture in a brittle one.
Oddly enough, a short bolt, tested to failure in a testing machine, will fail in the thread region due to the stress points inherent in the thread form.
Long bolts on the other hand, will fail in the shank.
This is usually explained by the idea that the bolt shank will break at its weakest point, and the longer the bolt, the more of the weak points, and the more of them, the weaker will be the weakest of them.
What is brownfield engineering construction?
In the Upstream Offshore Industry we consider Greenfield Construction to be the construction, installation and hook-up of a totally new facility. A facility that has never been in production, where there are no simulatinious operations such drilling or production in progress at the same time as construction activities.
Brownfield on the other hand is the addition of new facilities and equipment on an operating, producing platform. A Brownfield project usually means you are doing "Hot" work on a platform that is in production and may have drilling operations in progress.
Brownfield work can't be done in a "closed fence" environment so therefore is inhirently more dangerious and demands that you mitigate the risk.
An engineers vice firmly holds metal or wood so you can do whatever with it
What is an example of a Uniformly distributed load?
Zero amps on the neutral at the distribution panel.
In a real life example - a fish tank (full of water) the same size as the panel. The water evenly distributes the load over the entire surface area of the panel / shelf.

What is mean by plunger diameter in diesel engine?
Plunger is used in diesel engine fuel injection system which meters the fuel into combustion chamber. Higher the plunger diameter, higher the fuel injected into the cylinder. The plunger diameter of a typical diesel engine could be 9-10mm. Cam disk is connected to the plunger and each revolution, plunger will diesel 4 times into the combustion chamber.
Is reactive power a vector or scalar?
I am not sure what exactly you mean by "reactive power" (I guess you mean electrical reactive power), but power is the ratio of energy for a period of time. So that makes power (and reactive power as well) a scalar, since you can describe it with only one number. The fact that electrical reactive power is drawn on a XY plane, should not confuse you.
Where can you play football simulation game?
Pigskin Empire is awesome! I actually play myself, I started off as an OC in college at GT under another player who was HC. You can play Pro or college and even Canadian league. You train players, recruit, evaluate, run scrimmages, drills, salary cap, draft, in-home visits, live play calling during games, customized playbook, all kinds of things.
And its free! It's a good community of players and each season is about a month, and there's rankings, bowls, playoffs, etc. Try it out!
