DON’T disregard the thermal conductivity of the pipe 3.) Oil at 200 C flows in a pipeline. The pipe has a 30-cm diameter and the flow is at an average velocity of 2 m/s. A 200-m-long section of t...
8-31 Water at 10°C (p = 999.7 kg/m3 and μ = 1.307 × 10-3 kg/m.s) is flowing steadily in a 0.20-cm-diameter, 15-m-long pipe at an average velocity of 1.2 m/s. Determine (a) the pressure drop, (b) the head loss, and (c) the pumping power requirement to overcome this pressure drop. Answers: (a) 188 kPa, (b) 19.2 m, (c) 0.71 W 8-32 Water at 15°C (p = 999.1 kg/m3 and μ = 1.138 × 10-3 kg/m . s) is flowing steadily in a 30-m-long...
Problem 2 (10/30) - Steam at 180 C (saturated) enters a 10 cm diameter, 0.4 mm thick, 150 m long carbon steel pipe which is exposed to the elements. Air flows across the pipe at 10 m/sec. Air emperature is 20 C. Convective heat transfer of stem to the pipe is very high. Emissivity of the pipe is estimated at 0.8.Calculate the rate of heat transfer from the pipe. State any assumptions. Problem 2 (10/30) - Steam at 180 C...
Water at 10 °C (p = 999.7kg/m3 and μ = 1.307×10-3kg/ms) is flowing steadily in a 0.12-cm-diameter, 15-m-long pipe at an average velocity of 0.9 m/s. Determine (a) the Reynolds number and decide weather the flow is laminar or turbulent (b) the head loss, (c) the pressure drop, and (d) the pumping power requirement to overcome this pressure drop.
