Extracted text: Consider pressurized water, engine oil (unused), and Nak (22%/78%) flowing in a 20-mm-diameter tube. (a) Determine the mean velocity, in m/s, the hydrodynamic entry length, in m, and the thermal entry length, in m, for each of the fluids when the fluid temperature is 366 K and the flow rate is 0.01 kg/s. (b) Determine the mass flow rate, in kg/s, the hydrodynamic entry length, in m, and the thermal entry length, in m, for water and engine oil at 300 and 400 K and a mean velocity of 0.022 m/s. Part A Determine the mean velocity, in m/s, the hydrodynamic entry length, in m, and the thermal entry length, in m, for each of the fluids when the fluid temperature is 366K and the flow rate is 0.01 kg/s.
