[TR] Cooling

[Doug Mathews]

Folks,
I subscribe to Auto Restorer and there was  a letter someone wrote in on 
overheating. It sounds reasonable so I'll summarize and pass on and you 
engineers on the list can let us know if it is correct or full of "hot 
water"!

I quote here:
"The rate of heat transfer from the block to the water circulating 
through the block is based on the following equation: 
Q=mc(Tblock-Twater), where Q= the rate of heat transfer, m = the 
circulating water flow rate, c = the specific heat of water, Tblock = 
temperature of the water jacket walls, Twater = temperature of the water 
flowing through the block."
The writer goes on to say and here I paraphrase..../"if specific heat of 
the h2o is constant then the rate of transfer of heat from block to the 
circulating water depends on the flow rate and the temp difference of 
the block and the circulating water. If radiator is doing  its job and 
flow is increased, more heat is transferred from the block/(better 
pump)/. If flow is constant then a radiator with increased cooling 
capacity would be the answer to increased cooling capacity/."

So I deduce that you'd better start with a good radiator!
