Water at 30 °C enters a pipe of 25 mm in diameter and 1 m in length with a mean velocity of 0.06 m/s. The pipe surface temperature is 50 °C. What is the outlet temperature of water? Assume the fully developed condition. For water: k = 0.6 W/mK, ν = 0.8x10-6 m2/s, ρ = 1000 kg/m3, cp = 4187 J/kgK, Pr = 5
