Question

Engine oil enters a 1.25 cm diameter tube 3 m long at a temperature of 38OC. The tube wall temperature is maintained at 65OC, and the flow velocity is 30 cm/s. Estimate the total heat transfer to the oil and the exit temperature of the oil.

Robert · Accepted Answer

Finding Heat transfer rate and the exit temperature for the fluid flowing in the tube.
From the values of the fluid velocity, tube diameter and the kinematic viscosity of the fluid, the Reynolds number of the fluid can be determined as,
From the values of the Reynolds number the flow is laminar in nature.
From the Reynolds number corresponding to the laminar flow,
Nusselts number can be calculated from the following equation,
.
