Aug 16, 2018 · A Ton is 12,000 BTU PER hour, so I am not certain how you could have a "ton hour." Someone who does not know that time is already included in "ton of refrigeration" might say "ton hour," but adding the "hour" is not needed. Sort of like "irregardless."

It takes about 10 pounds per ton to accelerate to a speed of 6 miles per hour in one minute or 12 miles per hour in two minutes, a reasonable rate for a heavy train. Increasing this tractive effort increases the acceleration rate proportionately. The total tractive effort required for a train is the sum of these four components.

This rule is a quick way to approximate the cooling load for a room or building and may be helpful in estimating room air quantities. For example, to estimate the number of tons required to cool a 1,600-sq-ft home, multiply 1,600 by 1 cfm/sq ft to get 1,600 cfm of air.
The table below indicates air change rates (air changes per hour) commonly used in different types of rooms and buildings.

If a company’s capital intensity doesn’t increase, profit per employee is a pretty good proxy for the return on intangibles. The hallmark of financial performance in today’s digital age is an expanded ability to earn “rents” from intangibles. 3 3.
The measure of velocity is distance divided by time (fps), stated as feet per second. The measure of acceleration (or deceleration in this case) is feet per second per second. That assumes a reasonably good co-efficient of friction of about .75; better is .8 or higher while conditions or tire quality might yield a worse factor of .7 or lower.
