what is productive efficiency?

it is the term used by bureaucrats to align worker productivity with custodial transfer (production of goods). Accountants world wide have brought the term into the workforce through workplace agreements selling off holidays,work conditions etc for a pay increase which does not keep up with standard indexation of taxes.

P = d * Q * g * H * efficiency\nWhere,\np= power in KW\nd= density of fluid used\nQ= discharge\nH = head\nefficiency= given for a turbine

It is called the frontier because it represents the highest possible combinations of output given the current situation. It is the border between possible output levels and impossible ones.

I had a discussion about economies of scale about 3 hours ago.  In business, economies of scale means that in small quantities a number, i.e. profit, can be different than in large quantities.  In fact, in business, as your production increases efficiently (the term efficiently is important), your costs per unit decrease.  You take your overhead, which to a certain degree is fixed over a unit of time (usually a month or quarter is considered).  Then you take the overhead number and spread the cost over your manufactured products over that time.  When you manufacture alot, your overhead per item amount is low.  When you manufacture a few, the opposite occurs.  \n\nThis concept can be used in different disciplines and is largely universal.  Large quantities can be more efficiently produced than small quantities.

You measure the amount of fuel put in.  Using the flow of that fuel (cubic feet per hour), you then determine the amount of energy in each cubic foot of that fuel (or look it up - Natural gas is 1020 btu/cubic foot).  Then measure the amount of heat given off and the amount of electric produced.  \n\nEnergy out (Btu's) / Energy in (Btu's) = efficiency.  \n\nYou need to convert the electric out to btu's by multiplying the kW to Btu's (multiply by 3412).  With the heat given off, you need to determine the temperature of the exhaust and the amount of air flow of that temperature and that will give you the thermal side of the output.

Photosynthesis is about 1% efficient while we can make PV cells about 20% efficient.\n\nThis is yet another case of nature being inferior to human technology.

Depends on what you mean by efficient? Being that the purpose of the digestive system if to extract nutrients from food, how well it does that would be a measure of how efficient it was. Since the absorption of nutrients in the digestive system is dependent on the surface area of the intestines, if you were missing any of them you would be less efficient.

There is not sufficient information to calculate efficiency. \n\nFor an engine you need the energy input and the energy output. Energy output divided by energy input times 100 gives you the efficiency. \n\nThe amount of fuel and its energy content will take care of the input. The output requires a dynamometer or some other means of measuring the energy output at the engine shaft

Efficient is being able to get things done quickly. Sufficient means good enough.

Yes it is but not with the US Government in control. Efficiency has never been welcome on any government control ed or regulated business.  You see how they run a railroad don't you?

efficient capital market allows more money to be invested, which means more goods and services produced, which means lower prices. \n\nyou get more investment b/c efficient market has zero gap between the rate that users of capital pay, and the rate that owners of capital receive. In real world, this gap is non-zero, so less capital is supplied to the market; and less capital is demanded.

According to your question I am telling the way of increasing efficiency from manufacturing aspect only (not from considerations of hydraulic aspects).\n\nDo you remember Moody's Diagram and the Darcy-Weisbach Relation for flow through pipes in Fluid Mechanics? \n\nFrom Darcy-Weisbach equation frictional head loss is proportional to the friction factor 'f' (as the head develoved by the pump and discharge cannot be changed; also diameter nd length cannot be changed as it is considered in design part and not in the manufacturing section). So to decrease frictional head loss i.e. to increase efficiency, 'f' has to be reduced. Now, recall Moody's Diagram, for turbulent zone the friction factor depends on Relative Roughness.\n\nRelative Roughness = (Average Roughness Height)/(Diameter)\n\nDiameter is fixed from design considerations, so you have control over 'Ra'-value (Average Roughness Height) only. If the surface finish of the pipings are made better 'Ra'-value can be reduced. Thus efficiency will be increased.\n\n\n\nTo william l:\nThe diameter and length of tubings are fixed by the "Design Engineer" and not by the "Shop Floor Engineers". So a manufacturing section of a factory cannot increase or decrease the dimensions of the drawing at their will.

If you're talking about a job, then effectiveness is the ability of a person to do their job to achieve or even exceed the results expected of him/her.

A voltmeter and an ammeter will provide the input power. You will need some form of dynamometer to measure output power.\n\nOutput power divided by input power yields efficiency.
