THE BAKER FAN

The Baker Fan was developed by the Baker Co. as a load for running-in new engines and not as there seems to be a tendency to expound at the Reunions, as a device for the measurement of horsepower. There are two reasons why these fans are inadequate for such use. First, their performance is air density dependent, and second, the speed is relatively insensitive to the power input.



At higher elevations, the air is rarefied (less dense) and the fan spins more easily. Therefore, the power input to the fan would be less for the same rate of turning.

The normal air pressures at different altitudes are well known. From those values, I have calculated the change in air density with altitude and, in turn, the change in the amount of power required to drive the same fan at the same speed at three specific locations. If 50 horsepower were required to drive a fan at a particular speed at Rochester, N. Y. altitude (510 ft.), then only 48 horsepower would be needed drive the same fan at the same speed at Olean, N. Y. altitude (1438 ft.) and 40 horsepower would suffice at Denver, Col. altitude (5219 ft.).
