Consider the flow of oil at 10?C in a 40-cm diameter pipeline at an average velocity of 0.5 m/s. A 1500-m long section of the pipeline passes through icy waters of a lake at 0?C. Disregarding the thermal resistance of the pipe material, determine (a) the temperature of the oil when the pipe leaves the lake (b) the rate of heat transfer from the oil and (c) the pressure losses in the pipe. Assume the flow is hydro-dynamically fully developed.

A 10-mm diameter tube has a maintained surface temperature of 200°C. Engine oil enters the tube at 70°C at a flow rate of 0.5 kg/s and exits at 105°C. Find the length, in m, of the tube and well as the corresponding heat transfer rate, in W.

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...
