Show ton On Y.sr eight-hour trial she mads a. mean speed of 23.05 knots. Her coa expenditure for various speeds was plotted" VilE "surprising results. To go from 11.5 knots to 23 knots needed, roughly, 26.000." additional horse power, while the last knot alone absorbed 8,621' horse power. That is to say, to progress from 22 to 23 knots needed as much power as the total required to drive the ship at about 16 knots; or, to put it in still another way, the power needed to drive the Cape of Good Hope at full speed would, propel pro-pel two similar vessels at about 19 knots. The coal consumption at full speed was, roughly, twenty-six tons per hour; at 19 knots about 11 tons per hour. Again, at full speed the ship would steam 0.85 knot for each ton of coal burned, while at 19 knots the distance would be double for a similar consumption of fuel. " Enormous Cost of High Speed. The cost of extra knots of high speed was elucidated by recent experiments experi-ments with a new armored British erulser, Cape of Good Hope, of 14,100 |
