A 7 cm diameter bed on a 25 cm long bed, as shown in the figure below. The shaft rotates at 3200 revolutions per minute with uniform intervals of 0.2 mm. Continuous operation The temperatures of the shaft and bearing adjacent to the oil gap are 55 0C. your oil viscosity 0.05 N.s/m2 and its thermal conductivity is 0.17 W/m.K. Continuity, momentum and by simplifying the energy equations and solving for each separately, a) The maximum temperature of the oil, b) Calculate the heat transfer rates to the bearing and shaft.
This question about heat transfer/liquid. Obtain the following basic equations modeling natural convection in the two-dimensional plane at steady conditions in terms of the given dimensionless quantities. Note: The buoyancy term in the y-momentum equation will be obtained based on dimensionless numbers. Second photo gives you what you need.

A flat plate in an ambient at temperature Tꝏ received from a source the net radiant heat flux q” (fig. 3-52). The thickness of the plate d is much less than its length 2L; the third dimension of the plate extends to infinity. The heat transfer coefficient from the ends of the plate, if needed, may be taken to be h3 ≠h1 ≠h2. Find the temperature distribution in the system. Please type answer note write by hend.
