Hey All,
We want to design a water heater that works with a constant water flow in a pipe.
The pipe run in circles inside a water tank, the water in the tank is the heating medium.
We want to get an estimate of the required length pipe.
For this I take few assumptions:
[ul]
[li]surface temperature is the same at all length pipe
Water mass flow is constant
Water inlet and outlet is constant[/li]
[/ul]
And I am using these two equations:
Can I get an indication more or less or am I missing something?
Thanks!
