An iron plate of thickness (l) with thermal conductivity (k) is subjected to a constant uniform heat flux (q0) w/m2 at the boundary surface @ x=0. from the other boundary surface @ x=l, heat is dissipated by convection into a fluid at tꚘ with a heat transfer coefficient (h). solve for the temperature distribution within the plate, analytically and numerically and compare the two solutions given that: l = 2 cm, k = 20 w/(m.°c), q0 = 105 w/m2 , t[infinity] = 50°c and h = 500 w/(m^2°c).

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
