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?

Tc =    = 424.85 K

Explanation:

Data given:

D = 60 mm = 0.06 m

k = 50 w/m . k

c = 500 j/kg.k

HEAT FLOW Q  is

  = 47123.88 w per unit length of rod

volumetric heat rate

   = 424.85 K

how is this a question? in order for me to answer it i have to understand the question

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
