摘要:

Calculations were made of the time and distance required for a ship to accelerate to any fraction of its maximum speed, and are intended to serve as a guide in determining the length of run to be made in approaching the measured course in the conduct of ship speed trials. The effect of inaccuracy in the underlying assumptions was examined. Curves and tables are presented and offered as suitable for use.

摘要:

Readings have been taken on the eupatheoscope and compared with readings on thermometers and with readings on the A.S.H.V.E. effective temperature chart It was found that the mean of the readings on two thermometers, situated one at the floor level and one at the level of the head of a sedentary worker gave a value fairly close to the reading on the eupatheoscope. The general conclusion is reached that elaborate apparatus for reading comfort temperature is not justified until an explanation has been given of what constitutes the "freshness" of air, but that in Canada in rating comfort conditions more attention should be paid to temperature gradients, which are pronounced during spells of zero weather.
