Q $.$what is the final temperature of water

Given:

Water flowrate $=102gpm$

Water initial temperature $=250F$

Water specific heat capacity $=4182\frac{J}{k}gC$

Inner pipe dimeter $=2\mathrm{.}44$ inch

Outer pipe dimeter $=4\mathrm{.}55$ inch

Pipe material$=$ carbon steel

Gas temperature $=90f$

gas ratio pf specific heat $=1\mathrm{.}32c\frac{p}{c}v$

length of pipe $=3000$ feet
