A channel of square shaped cross section,30mm by 30mm, carries water at a rate of m = 2kg/s. The channel length is L= 10m and the inlet and outlet temperature of water are Tindide= 30C to T outside = 50C

1) if the surface temperature of the channel is maintained at Ts =90C, calculate the average heat coefficient h

2) calculate the total heat transfer rate

3) if the boundary condition on the surface changes from Ts = constant to q = constant, while all other input parameters remain intact, calculate q''. Note : heat convection coefficient is not an input parameter

4) considering q'' = constant , calculate the surface temperature of the channel outlet.
