Do you see anywhere the suggestion of KW/m2? No, then question not answered

No school, Stuff, I need to quote this for a client, were OEMs And Im just thinking of heat transfer principles Thx

Thanks MJ, Answering your questions: No nothing can be inside the tank and neither in the sides of it, neglect all heat loss from the walls. T1 = 15C T2 = 100C I just need an idea on the KW/m2 for the grill underneath the tank. My thought is the heat from convection plus radiation must...

Yes, i cant use immersion heaters it must be a grill underneath the tank. Its for 16000 liters and in 8 hours period. Thanks

Hello, Im trying to design an electric grill to boil water in an open tank. I need an advice on KW/ m2 to use for this purpose. Thanks, R

Hi there, I need to find design criteria for rectangular pressure vessels, anyone who could recommend me id appreciate it. I want to make a gas water heater with a rectangular water tank, around 180 psi design pressure. If theres a specific ASME code or design software please let me know...

Hi, Id like to answer how much time does it take to the coffee to cool to the surrounding air? I know the surface will cool from convection, but for example, what happens in the middle of the cup? If someone could advice in how to make a mathematical model for this Id appreciate it. Thanks

Thanks, thats what I thought but it is a bit counter intuitive and I needed to check it, the key part is the cold startup until thermal equilibrium is reached but delta T has to be the same.

Hi there, Im working in a water heater design and have a question that i think has to do with heat transfer theory. I have a 0.5 gal tank and a 10 gal tank both with same volumetric flow lets say 2 gpm, both with 12 kw of power( 2 heating elements of 6 kw each). How does the water tank size will...
