1(30%). a thin plate black body, insulated at the bottom is placed faced up in a room with wall temperatures of 30 c. air at 0 c is forced over the plate with a convective heat transfer coefficient of 12 w/m².c. calculate the plate temperature under steady state condition

Explanation:

The given data is as follows.

         Heat transfer coefficient (h) = 12

         Plate temperature () = = 303 K

         Steady state temperature () = ?

Hence, formula applied for steady state is as follows.

        =

Putting the given values into the above formula as follows.

        =

        =

                  = 282.66 K

                              = (282.66 -273)      

                              = 9.66      

Thus, we can conclude that the steady state temperature will be 9.66 .

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
