The short answer is:
Figure out how much is coming into the vessel and how much of that is flahsed to steam
Size the diameter of the vessel such that the...
This subject was covered some time ago in this thread:

However, I think it warrants additional discussion.
ASME BPVC Section 1, PG-61 FEEDWATER SUPPLY, PG61.1 (excerpt): “…each source of feeding shall be capable of supplying water to the boiler at a pressure of 3% higher than...
Secondary pump speeds should modulate in response to the remote secondary loop differential pressure signal. The set point will need to be refined after testing and balancing, but 10 psi is a typical starting point. The differential pressure signal is typically measuring the pressure difference...
Which standards should be specified in order to ensure quality pipe materials? I normally spec the grade, e.g. ASTM A106 Grade B, and the dimensional standard ASME B36.10.
Other than these, is there an applicable standard to ensure we don't get low-quality pipe on the project from a manufacturer...
Anyone out there have knowledge of how to fix a steel pipeline encased in a post-tensioned concrete slab?
The pipeline is 3” steel, welded joints, with one 90º bend. It carries hydraulic fluid at 200 psig for an elevator. The pipe is in a post-tensioned concrete slab in an outdoor parking...
Consider a generic parallel pump system in which flow can vary from 0 to 100% of design flow rate. Is there a "rule of thumb" on how many pumps is ideal? Which of the following arrangements has the lowest cost over the long term, conisdering first costs and energy efficiency?
- 2 @ 100% (2...
Does anyone know where the velocity limit values in the linked document come from? Hydraulic Institute standards? Other criteria?

Is radiographic examination (RT) applicable to socketwelds on piping? I have found sources on both sides.
Specifically, I'm concerned about a carbon steel (A106B, sch 80) piping system with class 3000 forged steel (A105) socketweld fittings, 1.5" NPS, handling high-pressure steam condensate...
