Water at 310 k and a flow rate of 4 kg/s enters an alumina tube (k=177wm k1) with an inner diameter of 0.20 m and a wall thickness of 0.02 m. air at a temperature of 390 k flows over the tube, heating it. the convection coefficients of for the water and air are 150 and 30 w m2 k-1, respectively.

can you make it more obvious. i can't see it properly

answer:

i answer later k
