### FUNdaMENTALS of Design

physics of power generation and transmission indicate that high speed and low torque are more efficient to create than low speed and high torque. The former is generated by high voltage and low current which is more economical than low voltage and high current. Once again, a transmission is often required to transform power into a useful form.

there are numerous ways to calculate a charging rate. The rate is usually obtained by timing how long it takes a compressor to fill a BA cylinder, perhaps an 80 cf SCUBA cylinder, from 0 to 3000 psig. The cylinder volume (80cf) is then divided by the filling time (5 minutes, for example). The result would be a charging rate of 16 cfm.
