24-Dichlorophenol | C6H4Cl2O - PubChem

The tube was intended to be used with an air sampling ,pump, capable of drawing air at flow rates of 10 to 50 ml/minute against vacuums of 0.5 to 5.0 cm of water. In practice, both sections were to be Soxhlet extracted with pentane for 6 hours, followed by 6 hours of extraction by methanol , and purging with dry nitrogen at 250 or 300 °C at a flow rate of 30 ml/min for 12 hours.

Gas turbine - Wikipedia

Blade-tip speed determines the maximum pressure ratios that can be obtained by the turbine and the compressor. This, in turn, limits the maximum power and efficiency that can be obtained by the engine. In order for tip speed to remain constant, if the ,diameter, of a rotor is reduced by half, the rotational speed must double.
