Saturated Steam - Conceptual Question

[vector2]

Following question is for concept only not an actual problem to solve.

Saturated steam is flowing in a 3" diameter pipe under a certain pressure (saturation pressure), temperature and velocity $$P ,T, v$$. The 3" diameter pipe expands suddenly to a 24" diameter pipe that is 10 feet long. The steam flows in the 24" diameter pipe and is then suddenly reduced to a 3" diameter pipe.

Question: Does the temperature of the steam go up as it expands in the 24" long tube?

Bernoulli and continuity are the only equations that seem relevant? How do I arrive at the new temperature in 24" section of pipe?

If the kinetic energy in the 3" pipe is negligible, there will be no change in the 24" section.
