What is the temp of the thermometer at 1 min? How long to reach 15 degree F?
Q. A thermometer is removed from a room where the temperature is 70 degrees F and is taken outside, where the air temperature is 10 degrees F. After one-half minute the thermometer reads 55 degrees F. What is the reading of the thermometer at t = 1 min? How long will it take for the thermometer to reach 15 degrees F?

A. Use Newton's Law of Cooling: T = T(environment) + (T(initial) - T(environment)) * e^(-r * t) where T = current temp T(environment) = 10 T(initial) = 70 r = rate of cooling t = time You know that after t = .5 min, T = 55. Plug these values in and solve for r: 55 = 10 + (70 - 10) * e^(-.5r) 45 = (60) * e^(-.5r) .75 = e^(-.5r) <- take the natural log of both sides -.288 = -.5r >>> r = .575 Now that you know r, solve for T at t=1min: T = 10 + (70 - 10) * e^(-.575*1) T = 10 + 60 * .563 >>> T = 43.8 degrees Likewise solve for t when T=15 15 = 10 + (70 - 10) * e^(-.575t) 5 = 60e^(-.575t) .0833 = e^(-.575t) <- take the natural log of both sides -2.49 = -.575t >>> t = 4.32 min

How much amps does it take to start a F-250 Diesel engine with a battery charger?
Q. I need to buy one but don't know how much amps I will need to turn over the F-250 7.3 liter diesel engine. Thanks for any info.

A. You will need a lot more amps than 1 battery charger on start will provide. Usually it takes about 400 amps to get them puppies to think about starting.. depending upon the 7.3 (If it's a powerstroke it needs a lot more power to boost up the oil pressure to fire it off) Usually it takes 2 battery chargers, but usually a stone dead Ford diesel takes 2 professional jump start batteries to kick them over good. If you are willing to wait to charge the batteries first, any battery charger will work (preferably one that can charge at 40 amps or so continous , but be prepared to wait half a day to start it if the batteries are still good)

Asked by Constante M - Sat Aug 11 09:55:05 2007 - - 1 Answers - 0 Comments

A. The frame, box, etc. are all made of aluminum. The empty weight is 17,500 lbs. The Pratt & Whitney JT3C weighs 3,875 lbs. (subract the engine weight from the empty weight to get the shell weight) The motor has a lot of titanium blades but the bulk of the weight is aluminum and stainless steel.
