- Water flows at Too₁ = 50 °C, hoo₁ = 3500 W/m² ° C in a pipe with = 1.25 cm, r2=1.33 cm and L= 1 m, the pipe has k= 16 W/m C. The outside of the pipe is exposed to a fluid with Too2=20° C, hoo₂ = 7.6 W/m²° C. Calculate the rate of heat lost by the pipe and find the temperature of the pipe outer surface T₂. Park L 8(51)
