U-tube heat ex-changer

A U-tube heat ex-changer.

Heated water of 400° Kelvin transfers the heat to the water flowing through the copper tubes and visa versa. Heating the water in the copper tubes with Δ25 ° Kelvin

A low inlet velocity of 0.15 m/s for the media flowing through the tubes and a velocity of 0.3 m/s for the media flowing in the outside tank. Heat conduction of 15 W/m² at the outer surfaces to simulate the temperature heat flux through the tank.
