On a truck fitted with a transfer case, when you start the truck it is automatically engaged in the 4 X 2(high speed mode), you can now change to 4 X 4 (high speed mode) or 4 X 4 (low speed mode). but there is no option of engaging the 4 X 2 (low speed mode).
Why is it like that???

If I want to write down a heat balance equation for a control volume where some chemical reaction is goin on then how correct will it be to say that the heat generated within the control volume is equal to the enthalpy of that reaction.
We are not very concerned in finding the temp at various depths.Because of the system used for aereating the compost heaps, we can only lay the pipes at the bottom of the pipe.
The temp at the bottom can be calculated easily by measuring the temp of the air that is sucked from below the heap...
Indeed I am measuring the rate of heat transfer from the compost to the running water in the pipe. Although as we proceed with the experiment we would like to know the total heat generated by the compost in a given time.
For those who say that I will end up slowing the composting process. The...
Hey Dave thanks for the reply...
during composting the temp of the compost heap crosses 70 degrees and remains like that for about 2-3 weeks. and it is this heat that we plan to trap..
the problem we are facing is when we dig to bury the pipe...the compost loses the heat to the...
I am doing a test to find the heat generated from a heap of compost.Is there an equation which gives me the rate of heat transfer. I am using a pipe buried in the compost heap. The inlet and outlet temp. of water is know and so is the mass flow rate. The specifications of pipe ie diameter and...
