How long should foam dissipate after the turbine is stopped?

Explanation:
Foam needs time to break apart and drain away after the turbine stops so nothing foamy is left that could be drawn into the engine or interfere with sensors and seals when you restart. Giving it a short, proper wait allows the majority of the foam to dissipate from critical paths, reducing the risk of foam ingress or contamination. If you rush the restart too soon, residual foam pockets can remain and cause problems; waiting too long wastes time without adding safety. The chosen option reflects this balanced timing—long enough for foam to dissipate, but not so long that maintenance gets unnecessarily delayed.
