Heat transfer in a pipe flow

Dear all,

kindly help me with the following problem.

Pipe ID = 300 mm

Pipe OD = 320 mm

Pipe Length = 15 m

 

Fluid = steam

Pipe material AISI 1330 (density = 7870 Kg/m^3 | Sp. heat = 472 J/Kg K | Th. conductivity = 51.9 W/m K)

 

Available Boundary Conditions at Inlet are:

Mass flow = 90 tons/hr

Velocity = 17m/s

Pressure = 64 Bar

Temperature = 480 Celsius

 

Assumed film co-efficient = 14.5 W/m^2 K

 

I have solved the problem, but the outputs are not as expected. Also the flow trajectories are not reaching the exit point.

What kind of settings to be followed throughout.

Can you kindly help me in solving the problem.
