Box strength is measured in two different ways. The mullen test measures resistance to rupture in pounds per square inch (psi). Linerboard constitutes the bulk of the bursting strength of a corrugated sheet. The basis weight of the paper as measured in lbs/1000 sq. ft. directly impacts paper strength. Some of the standard basis weights of mullen grades include: When the corrugated box industry was new, most shipments were made by rail.
How much meat does the average American eat annually? 50 pounds (20 kilograms)? 100 pounds (40 kilograms)? Not even close. If we look just at the livestock âBig Fourâ â cows, chickens, pigs and sheep â the average American adult consumed 90 kilograms (198 pounds) of meat in 2014, according to data from the Organisation for Economic Co-operation and Development (OECD). The global average during that same year was 34 kilograms (75 pounds).
To summarize, the average American consumes about 2000 lbs of food per year, which works out to about 5.5 lbs and 2700 calories per dayâor nearly your entire body weight in food per month. Divide those daily 2700 calories by 5.5 lbs and you get 490 calories per pound of food, on average.here is no gain in meat produced per acre by feeding grains to ruminants compared to feeding on pasture. Pasture is much more productive in terms of plant biomass yielded per year than corn since the plants are perennial and grow actively year-round in many areas.
