Hi there,
Hopefully this is a very easy question and you all can just confirm this for me.
When calculating heat transfer into a fluid from a heated tube, is it correct to say that the heat transfer coefficient is *not* dependent on the tube diameter?
So, if we solve for T_{out}, we get...
I'm setting up a thermal resistance network to determine the heat loss through the insulated wall of a heated fuel/crude oil tank but i cant seem to find values for the convective heat transfer coefficient of the fuel oil (kerosene) or the crude oil at elevated temperatures. I have only found...
Hello, PF! Recently, while reading chapter 10 (microscopic energy balances) of the second edition of BSL, I found a minor discrepancy which is confusing me, especially when considering the mathematical analogies of heat and mass transfer.
In section 10.1, the authors introduce Newton's law of...

I am working on a model for predicting cooling in a system that evacuates a vessel and cools by evaporation of water and the water vapor is condensed in a tube and shell heat exchanger. My concern is the prediction of the steam side heat transfer coefficient as the air is removed from the...
Hello,
I have a swimming pool with a waterfall feature.
I need to know how much does the waterfall contributes to cooling the pool.
I tried to use Newton's law of cooling, but I have a problem with the Heat Transfer Coefficient in this case.
Following are the Givens:
Waterfall Width= 5m...
Hello all.
I need to design a radiator for 43kw heat dissipation. I have used the LMTD method for finding out the contact surface area of the radiator. But I have a small problem. I cannot find the area unless i know the overall heat transfer coefficient. Can somebody please give an estimate of...
Not sure if I'm getting this right, my answer seems very small, can anyone advise?
Question- butanol at a temperature of 28oC is pumped at a velocity of 14ms-1 through a 100mm diameter tube kept at a wall temp of 90oC. The properties of butanol are below. Determine the convective heat...
Hi, ive recently been given a series of questions on heat transfer to do and have done most of them with general ease, but this one question ive been stuck on for ages and i cant seem to figure out:
"A double pipe heat exchanger is made up from a length of 25mm i.d. steel pipe of 2.5mm...
1) PROBLEM:
Task is to find the thermal conductivity of steel experimentally.
I have conducted relevant experiments and I am trying to solve for the thermal conductivity (k) itself. My final however is ten times too large in size, and I am having trouble identifying where the error is coming...
