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!
