For accurate cost estimation you will need to find a vendor and have them supply you a "budgetary quote" for your 700 kW boiler. The vendor can usually get this type of quote to you more quickly than a firm quote because they are not held to that price or terms; though I find that frequently the price is the same when we go to purchase. When I need an ...

Where does the power for a wind turbine come from? Answer - the wind. So how do you get 15kW from the wind rather than 11kW? Answer - you either need a location with a higher wind speed, or you need to pick up more wind, i.e. the blades need to be longer. How does this affect cost? Answer - a longer blade needs more material for its extra length. But then ...

You measured one load to take 1.8 kWh. That implies that 7 loads would take 12.6 kWh. If these 7 loads are repeated 52 times per year, then a whole year of operating takes 655 kWh. As a sanity check, 1.828 kWh over 1 hour and 13 minutes comes out to 1.5 kW, which is plausible for some type of clothes dryer. \$0.33 per kWh sounds very high, but going with ...

Machinery manufacturers provide a maintenance schedule, just like car manufacturers give you a service book. Once you have that then you can estimate the time required for each service operation, whether it is an inspection, lubrication or strip/rebuild. So: Hours_Machine_1 + Hours_Machine_2 + ... = Total hours / year Once you have that you can then work ...

If this is a student design problem to see whether you understand the principles, make it as easy as you can, use steam and cooling water. Calculating all the pressure drops on the weird pipe systems and valves you need when using one stream to cool/heat the others will drive you insane. Not to mention what it can do to your choice of materials of ...

Cost is not usually the deciding factor. Usually we need to keep the fluids separate for a reason: one fluid needs treating the other doesn’t Or the systems are at different pressures Or the fluids need to be different due to later use.

Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis." "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements." With ...

Ok, since nobody answered, I investigated this more on my own. Note: the answer is just an estimate and might have incorrect assumptions. In particular, I'm assuming 400 kV means 400 kV line-to-line voltage and not 400 kV line-to-neutral voltage, and I'm also assuming the voltages and amperages are RMS and not peak. These assumptions, if incorrect, change ...

There are many points which directly affects the cost of wind turbine. Before installing any wind turbine plant for 1 to 2 years of data analysis of wind density , direction and speed are done by engineer for success of plant which require money and resources. Plants needs lands for installing turbines also land cost depends on market scenario. Height plays ...

The amount of information you specified is too limited. If you had more information, maybe you could do it, but not as stated. Machining tasks can vary greatly. I can imagine some parts where it might literally take hours to get work piece fixtured in the machine, but then the actual machining operation takes only a few minutes (e.g. a giant part for a ship ...

No, because the number to be produced changes the percentage ie the setting up time can be longer than the machining time for 1 piece but 3% for 100 pieces and 0.003% for 1000 pieces...

As Mahendra Gunawardena said, there's not one universally used method of pricing manufacturing projects, but there are some pretty common facts that result from the economics of the situation. Firstly, if you're talking about small runs at a large company and the design doesn't include anything exotic, the pricing will probably have less to do with the ...
