Question

Transcribed Image Text:Current Attempt in Progress
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 0.014 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 0.018 m/s.
Part A
Your answer is incorrect.
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 0.014 kg/s.
