Could not achieve the Constant Velocity?

Hello all,
I am trying to simulate a simple two-conduit model. It is a straight double pipe with a length of 5 cm. I want to do thermal analysis at a constant velocity and check heat transfer for different velocities. But when I specify velocity inlet and outflow outlet or pressure outlet. There is an increase in the velocity at the outlet. I would like to take the suggestion to solve the issue and achieve the same velocity at the outlet as an inlet. Thank you in advance Raj |

Does the density change with temperature?
Compare the mass flow rate at the inlet to that at the outlet. Only worry about mass imbalance. |

Yeah, density has a very slight change and can be ignored. But, in my model phase and velocity being constant is a priority as it is solidified melt.
