Transcribed Image Text:

The fluid entering a pipe with a wall thickness of 3 mm, an inner diameter of 10 mm, 100 m at a speed of 1 m/s is cooled to a temperature of 75 °C. Apart from the pipe, there is a heat transfer coefficient of 7.8 W/m2.K and cross flowing water. a) Calculate the heat drawn from the fluid. b) Is the fluid flow laminar in the pipe? Is it turbulent? Why? c) Calculate the heat transfer coefficient between the fluid and the inner surface of the pipe. d) Calculate the thermal resistance of the inside, outside and wall of the pipe. 2637 J/kg.K Fluid: Nup = 0.023ReP-0.3 kg/m³ V= 3.15 x 10 m²/s pipe: kpipe 240 W/m. K = Cp H p=1079 Pr 34.35 k 0.261 W/m. K The fluid entering a pipe with a wall thickness of 3 mm, an inner diameter of 10 mm, 100 m at a speed of 1 m/s is cooled to a temperature of 75 °C.
