Heat transfer

in a test in a double tube heat exchanger the following data areobtained
For hot fluid
Flow = 11.6 gal / sec
Outlet temperature = 30.1 ° C
Inlet temperature = 32 ° C
For cold fluid
Flow 11gal / min
Outlet temperature 25.1 ° C
Inlet temperature 24.2 ° C

For the fluid consider
k = 0.49 w / mK
cp = 3729.95 J / kgK
Prandtl number = 14.29
Density = 1035.02kg / m3

Get:
1) the interior and exterior convection coefficient
2) The heat transferred and the average log temperature
3) Area

Explain your procedure as widely as possible.
