For example, at about 15% full load speed the required torque typically is around 5% or 10% full load torque. As shown below, the pump torque-speed curve follows the square law Overlaying Torque-Speed Curves to Match Motors to Pumps. Like pumps, motors produce a torque-speed curve of their own.

Gear Train : Gear Ratio, Torque and Speed Calculations. A Gear train consists of two or more gears in series. It is used to increase or decrease the speed or torque of the output shaft. The term Gear Ratio is used to calculate the speed and torque of output gear when torque is applied to the input gear. Spur Gear in Motion.

(ie., for various speed of the compressor the flow rate Vs Discharge pressure curves change accordingly) As per the curve, the point (1) represents the 100% speed (also called rated speed) of the curve and the point (1A) represent the maximum continuous speed of the compressor. In this case, the maximum speed is 105% of the rated speed.

A torque rheometer is a batch mixer that measures the torque applied to the mixing blades as a function of the mixing time. It is widely used in laboratories working on polymer processing. Using torque to obtain other fundamental pieces of information, like viscosity, can be of great help, not only to the scientists, but also to the industry.
