I just did power calculations for my "super fast light battlecruiser". As I previously mentioned, the specs were:
light displacement: 32,000 tons
normal displacement: 33,500 tons
dimensions: 800ft x 85ft x 29.7ft (45ft hull depth)Cp: 0.60
Cm: 0.97
I had hoped that 510,000 SHP could be generated and delivered (somehow). The ship is probably too short for what was attempted, as a longer ship that was less full would reach higher speeds for less power (up to a point).
This is some of the power curve data:
- 25 knots: 60,404.6 SHP
- 26 knots: 67,869.1 SHP
- 27 knots: 75,832.5 SHP
- 28 knots: 84,305.9 SHP
- 29 knots: 106,515.0 SHP
- 30 knots: 135,587.0 SHP
- 31 knots: 166,478.0 SHP
- 32 knots: 199,153.0 SHP
- 33 knots: 233,762.0 SHP
- 34 knots: 270,231.0 SHP
- 35 knots: 308,512 SHP
- 36 knots: 348,665 SHP
- 37 knots: 390,772.0 SHP
- 38 knots: 434,861.0 SHP
- 39 knots: 480,793.0 SHP
- 40 knots: 528,651.0 SHP
