I would like to confirm if heat-transfer coefficient α units in SI are W/m2 K. I have to use heat-transfer coefficient α in this formula:
Heat-transfer resistance: 1/k = δ/λ + 1/α
Where δ is material thickness and λ is thermal conductivity
It's possible to calculate the latent heats of fusion and the specific heat of a solution of H2O and NaCl?
In some cases, it would have two latent heats of fusion? For example, at 10% NaCl, one at -21ºC and another at -5ºC?
Hello everyone, first of all, thank you very much for reading.
I have to design a container (100 mm of height and 80 mm of interior radius of XPS) to keep a cryogenic mix (water and salt ice) at -15ºC at least for 40min. And my problem is to calculate the optimum thickness of XPS.
