Personally, I love the Striker, MegaTraveller and FF&S design systems for their crunchyness and real-world units, but I recognize that I am in the "gearhead" minority.
So what about adopting the trend of the MongooseTraveller Vehicles book and T5 Makers in restructuring it more towards a result-oriented system than an assemble the components system?
It would be nice to see a 'maker' that uses real world units (kilograms, kiloliters, kilojoules).
If you like and want to use design sequences, at least make sure you do some fairly good research first, and derive the sequence from some actual equipment. Going back to the Wet Navy Article series in Challenge Magazine, which uses the MegaTraveller vehicle design sequence as a base, the following is stated. The material is copied from the Challenge #53 that I purchased and downloaded from DriveThru.
Pumps are rated by the number of kiloliters they can pump per hour. Pumps take up hull volume at 10% of their rated pumping capacity in liters. They weigh 10% of their rated capacity in kilograms.
As an example, a pump with a capacity of one kiloliter per hour has a volume of 100 liters and weighs 100 kilograms.
One kiloliter per hour of water is equal to 1000 kilograms of water, or for my ancient English units mind, 264 gallons per hour, with a volume of 100 liters being equal to 26.4 gallons or about one-half of a 55-gallon drum. The weight should be 100 kilograms, or 220.5 pounds.
Now, in my basement, I have a submersible back-up pump for my sump pump, purchased at Ace Hardware. Its rated capacity per hour, with a 15 foot head, is 660 gallons, or just about 2500 liters. According to the design sequence given, the pump should occupy a volume of 250 liters (66 gallons or considerably larger than a 55-gallon drum), and weigh 250 kilograms or about 550 pounds. The pump that I have is rated at 1/6 horsepower, weighs about 7 pounds, and could fit inside of a One gallon milk container. It is powered by electricity, but then the article allows for that.
So, again, if you want to have detailed design sequences, do some research first, in the Real World, if possible.
