The condensers served two purposes, they turned the steam back to water to be reused and they created a vacuum that enabled the engines to extract much more energy from the system. One shaft of the Titantic was powered by a turbine that recieved the steam from the two triple expansion reciprocating engines at 9 psi and developed 16000 hp from a pressure drop between 9 psi and about 28 inches of vacuum. The evaperators made fresh water from salt water to replenish losses in the system and provide water for the crew.

It's just appeared to me: the KH's are expetrimental ships, after all?

So, it's quite possible that this definite unit (on the art) is the second, or third ship of the class, with certain differences from the original. ;) That's why it have six smoke stacks, two masts and others. After all, even if the Inner Circle IS convinced that they build the optimal design, the simple sea engineers and officers couldn't knew that.

So, it is pretty possible that the KH's would be really different from each other "in hope to find the optimal solution". ;)

The higher the pressure the smaller the piston needed to provide the same force it's a direct part of the equation IE F = P x A re-arranging A = F / P thus the higher the P the smaller the Area of the piston needed ;) In a closed system you lose water, the crew drinks it, the whistle vents steam to the atmosphere, leaking stuffing boxes on piston rods vent steam to the atmosphere etc. Provision to clean out tubes will increase the useful life of a sea water using boiler.

It may be true for British Empire, that have a sufficient repair capabilites on Malta, Canada, India, Australia and Hong Kong. But for Charis, who haven't ANY forward industrial base sufficient to this kind of machinery, it would be pretty hard to replace or even simply repair the boilers out of Delthak.


Condensing steam engines deliver more power for the same fuel consumption because the exhaust pressure from the low pressure cylinder approximates a hard vacuum as opposed to the atmospheric pressure (at best) that a non condensing engine can manage. If you have a heat sink like the ocean then going condensing is a no-brainer. Condensing engines provide a steady supply of recycled fresh water so feeding fresh water back to the boiler is equally good sense. A for make up water, if you want to make long ocean voyages then you need fresh water for the crew if no-one else, so you either have a large water tank (which weighs a lot - a couple of tonnes of water a day for a typical crew) or a small flash boiler and condenser (even if you don't have a steam engine - these were integrated with the stoves on the 1700's sailing ships).
Fresh water lets you use carbon steel for boiler tubes as opposed to the Admiralty Bronze or stainless steels you need for a salt water charged boiler.
Salt water also has a higher boiling point than fresh water so uses more energy to boil and the resulting brine left in the boiler must he continuously dumped overboard through the mud drum drain (with the loss of heat in this path as well). So unless you are making table salt as a byline, salt water boilers in marine use are rare for good reason.

Interesting question: assuming that Dohlar would survive the war intact, and it's own industrialisation wouldn't take more than 10 or 15 years - what could they build to put against KH's?

Did you want to use "utilis est" as it is useful to? Then it should be "utile", as "it" is neuter, and be constructed with infinitive hence "conquirere". I suppose "auctor" is the object to "conquirere" therefore it should be "auctorem" as conquirere uses the accusative.
I wonder why the subjuntive in "sciat".

One thing seems clear to me from seeing this: it will scare the hell out of any non-Charisian naval personnel. Even those who saw the ironclad river barges (and survived) will find this a different and even more scary ship.

I'll be curious to see how many of the CoGA ships continue to attack when they are brought under accurate fire at several thousand yards.

I really doubt that any CoGA ships would be operationg outside coastal waters against that ships. They would attack at night, or in straits and gulfs, were the space is limited. So, the range advantage of KH would be more or less theoretical, than the effect of 8-inch shells on unarmored wooden ships.

That's why they need some riverboats or somthing smaller to scout and to act as shields.
