You have to have a motivation to type fast. I took years of typing in elementary and high school in the 80's and 90's and was always more comfortable hunting and pecking. When I went to college, AOL instant messenger came out. I could not keep up with the conversations. So, I forced myself to...
This is a helpful white paper on the subject:

Normally margin is added to the pump power, not head or flow. You mention MVR, are you referring to ABS MVR? I do not see the 10% requirement in those rules for bilge pumps.
If you know the flow at 170 ft of head and the dead head, you can build a reasonable curve. I suspect your contractor only really needs the dead head value for the stress analysis.
Not there so I don't know.
But in general, there are three prongs to good work: effort, efficiency, effectiveness. Working hard is only one part of the story. Is what is being produced efficient or effective?
The other part of the story may be soldiering. I have probably been guilty of that...
Not sure how your program works, but unless the water on deck is separated from the water the vessel is floating in and trapped as to add to the dead weight, it is contributing to the buoyancy of the vessel.
Are your plots perhaps mislabeled?
JStephen, CWB1,
I noticed years ago that there are at least two different types of a university approaches. One teaches the physics and the theory and lets the students apply them as applicable when they venture into the real world. The other teaches existing, proven solutions.
I had a similar...
Thanks for the input SPLD310. It is a vital system as defined by the CFRs. The treatment plant, while not part of the original, approved system is now required by retroactive international regulation. As an alternative, I am looking at manageable pipe spools with victaulic couplings. Could you...
itsmoked, yes, I have read the regulation. I agree on the ship's fuelling lines. If use of those kinds of hoses are specifically called out as an exception somewhere, that would help my case.
Thanks KevinNZ, that's the regulation alright.
Thanks hydtools, I was hoping not to go there. I could...
