There is no problem: simply a statement of the amount of ice an ice machine can produce in an hour!
about 150-200 lbs
The average Bobcat weighs between 4000 and 5600 lbs. This is a very heavy machine and it often has a lifting capacity of 2200 lbs. However the lifting weights may vary depending on the machine.
Ice.
As atoms in water cool, they align to form a crystal (ice). This causes the space between molecules to increase, so the water expands. You get less molecules in a cubic inch of ice than you do in a cubic inch of water, so you get less weight. Ice is about 9/10ths as dense as water, so a gallon of ice weighs about 10% less than a gallon of water -- about 7.2 lbs. v. 8 lbs.
This information should be available on the Boeing website or other avaition-related websites. For a quick answer, I will related my experiences from 1970's. Boeing certified the B747-200 to operate with General Electric CF6-50 engines. During take-off power, each GE engine could produce 56,000 lbs of thrust per enginer: or 224,000 lbs for a few minutes. Now, the larger B747-400 a/c have more powerful engines. Currently each engine on a Boeing 747-400 can generate a maximum of about 63,300 lbs of thrust. Accordingly, since this aircraft has four engines it can produce total thrust of about 253,000 lbs.
The price of a brand new commercial ice maker depends on the brand and size of the machine. A brand new Manitowtoc 1385 lbs. Nugget Ice Machine costs $6595.
Depending on the temperature of the ice block and the consistency of the shaved ice, 10lbs of ice can make roughly 24- 36 cups of ice. This amount also largely depends on the machine used. If you are using a commercial planing/shaving type machine you can expect to see results around 36 cups. If you are using a small household machine, you can expect results around 24 cups, maybe lower.
about 150-200 lbs
1983 lbs max with 30 gal of water, 30 lbs of propane, and 25 lbs of ice for ice box or refrigerator.
23.15 lbs, plus ammunition.
Clear ice weighs about 7.6 lbs per gallon so 21 gallons would weigh about 160 lbs.
