Along rod of 60-mm diameter and thermophysical properties rho= 8000 kg/m3, c= 500 j/kg·k, and k= 50 w/m·k is initially at a uniform temperature and is heated in a forced convection furnace maintained at 750 k. the convection coefficient is estimated to be 1000 w/m2· k. what is the centerline temperature of the rod when the surface temperature is 550 k?

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

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.
