One of the most important management decisions is matching equipment size to acreage, says Edwards, the Iowa economist. A 2006 University of Illinois report shows a 20% drop in owning and operating a 340-hp. combine when you farm 3,000 acres vs. 2,000 acres (from $28.70/corn acre for 2,000 acres to $22.60/corn acre for 3,000 acres).
In previous articles, we discussed best practices on "how to size an air compressor", as proper sizing is important to meet the demand your facility requires.When it comes to sizing of an air receiver, a good rule of thumb to remember is to allow 3-4 gallons for each CFM or 10-15 liters for each liters/second of compressed air depending on the type of an air compressor used and the ...
One aspect of scale economies which has received more attention in the engineering than in the economics literature is the "0.6 rule". This rule has its origins in the relationship between the increase in equipment cost (C) and the increase in capacity (V) given by C 1 /C 2 = (V 1 /V 2) α where α denotes the scale coefficient.A value of α less than unity implies increasing returns to scale.
