| Show I 1 COST OF STEAMSHIP SPEED extra knot per hour Is a costly honor for atlant liner the extra knot of speed or fraction of a knot which each newest atlantic liner must achieve over her sor of a few months before Is a terri bay costly honor just how costly it Is Is explained in the 1903 4 edition of rhodes steamship guide say that 1 horse power gives a speed of 16 to 17 knots and 2 horse power gives 21 knots from this point the effort required to pro duce each additional knot is enor thus 3 horse power only gives 28 knots and 4 horse power gives 26 knots and the next six knots would mean almost a doubling of the power it might be possible says the writer by the luggage and asing metal of high tensile strength to reduce the weight of a 22 knot merchant steamer to 14 tons but unfortunately passengers must have their luggage with them the best and ample provision must be supplied malls must be carried and a little precious cargo so that the di placement is increased at least 3 tons or so with the result that the powe required for the speed of 22 knots amounts up to such an ex tent that the consumption of coal equals a ton per mile traversed and the ectra load of 3 tons costs in coal alone for the atlantic trip some |
