Coldest temperature The average body temperature is 98.6 degrees Fahrenheit. At an internal temperature of 95 degrees, humans can experience hypothermia, shivering and pale skin. At 86 degrees, they become unconscious and, at 77 degrees, cardiac arrest can occur.

It turns out, that just a degree or two difference in temperature makes a big difference in your heating or cooling bill. That means you can save between $1.80 and $2.70 a month by raising the temperature one degree and as much as $9.00 to $13.50 by raising the temperature five degrees.

Experts in air navigation have a rule of thumb known as the 1 in 60 rule. It states that for every 1 degree a plane veers off its course, it misses its target destination by 1 mile for every 60 miles you fly. This means that the further you travel, the further you are from your destination.

b) To determine the pipe slope, subtract the two manhole inverts and divide the difference by the pipe distance and multiply by one hundred (100) to obtain the percent grade of the pipe.

The roof’s pitch is the angle of the roof, usually presented as the inches of vertical “rise” over 12 inches of horizontal “run.” Generally anything above a 7/12 is considered a non-walkable roof and requires some extra equipment and usually some extra cost to the customer.
