i have this example problem...and i want to know how to answer this problem :confused:

a carnot engine is operated with its maximum temperature equal to 700K and 300kW were rejected. what is the sink temperature, if 450kW enters at the upper temperature.

tanx for your help..

actually i have no idea what carnot engine is all about...i look for some formula but its not related with the problem...:frown:
 
You can not go about learning science by plugging numbers into formulae without understanding the principle involved. You must first understand what a Carnot Engine is before you can attempt to answer this question.

I'm sure the recommended textbook for your course will cover this.

Thread 'Modeling a graph that shows age in relation to depth of an ice sample'

To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
