5. (8.27) Circulating hot air through a pipe immersed in colder water is a rudimentary technology for air conditioning. If air at Tair ,i=29∘C and a volumetric rate of 0.025 m3/s is routed through a polymeric pipe (thermal conductivity=0.15 W/mK,ID=0.15 m,OD=0.17 m ) that is submerged in water at Tw,inf=17∘C, and a convection coefficient of hw=1500 W/m2 K, calculate the pipe length L needed to provide an outlet air temperature of Tair,o=21∘C. What is the fan power needed to move the air through this length of pipe? Consider no friction losses.
