The operator must determine what steam pressure on thegauge will give the desired speed to the tester. When operating a hand-driven tester the number of revolutions which thebottle makes, to each revolution of the handle, should be determined by diameter of the circle described by the bottom of the bottle when in the horizontalrunning position should be measured. By consulting the above table, the requiredspeed of the bottle is obtained. The number of revolutions per minute required asindicated by the table is divided by the number of revolutions the bottle goes to eachrevolution of the handle. The result will be the number of revolutions of the handleper 7
