Qurstien I Oil flow in a joumal bearing can be troabod as paralict flow betwoce twe large mothemul plats with ane detentine the followieg: a. The velocily and icmperatiec diatributions in the ol b. The matirtum ternperature and whare it oecur E. The heat flus from the oil io each plate la Quectien 2 The top surlace of a metal plate (k.n =237 Wim K) in being cooled by air (2,=0.243WiKC ) While the botiom suface is exposed to a hot steam at 100 CC with a convection heac transfer coefficient of 30WIm2. It the bothom surface temperature of the plube a sorC. setermire the semperature gradient in the ar and the temperatioe gradient in the plate at the top surace of the plate. Question 3 (Problem 6.13, trsibesk) If laminar flow is induced at the surface of a dick doe to rotation about in mas. the local convection coefficient is known to be a constant h=C, independert el raduas. Contider conditons for which a disk of rades r2=100mm is rotating in stagnart air at To 207C and a value of C=20WIm2K is maintained. If an embedded electric heater maintains a suface temperature of T4 a 50 .C. What is the local heat flux at the top surface of the disk? What is the total electric power requirement? What can you say about the nafure of boundary layer development on the diak
