Engine oil flows through a 25-mm-diameter tube at a rate of 0.5 kg/s. The oil enters the tube at a temperature of 25°C, while the tube surface temperature is maintained at 100°C. (a) Determine the oil outlet temperature for a 5-m and for a 100-m long tube. For each case, compare the log mean temperature difference to the arithmetic mean temperature difference.
- EXAMPLE 8-1 Laminar Flow in Horizontal and Inclined Pipes Consider the fully developed flow of glycerin at 40°C through a 70-m-long, 4-cm-diameter, horizontal, circular pipe. If the flow velocity at the centerline is measured to be 6 m/s, determine the velocity profile and the pressure dif- ference across this 70-m-long section of the pipe, and the useful pumping power required to maintain this flow. For the same useful pumping power input, determine the percent increase of the flow rate if the pipe is inclined 15° downward and the percent decrease if it is inclined 15° upward.

For seaworthiness trial of a new ocean-going vessel design, the total convective heat transfer rate of a fully turbulent water flow over a 10-m×2-m side of a flat plate was measured to be 77.2 kW under a specific steady condition in a test setting. The conditions are: velocity of the water is 0.5 m/s along the 10-m side of the surface; water temperature is 18°C; and surface temperature was uniform at 22°C. What is the friction force (skin friction drag) due to the water flow on the surface?
