Based on the ratio peak workload/peak V[O.sub.2], mechanical efficiency
was lower among the subjects performing the stepwise protocol (p = 0.002).
Wet-laid fiberglass media provides good mechanical efficiency
for particle capture, while synthetic filter media typically offers better durability--especially important in avoiding damages to very expensive filters.
and volumetric efficiency can be calculated as follows:
Maximal oxygen uptake (V[O.sub.2]max), gross mechanical efficiency
and the lactate threshold, defined as the percentage of V[O.sub.2] max that an increase in blood lactate concentrations above baseline levels occurs, are determinants often used to assess endurance ability.
The mechanical efficiency
was found to be around 94.2%.
The new gen-sets are available in a 60 Hz configuration operating at 1200 rpm and rated at 1.6 MW, with an ISO mechanical efficiency
of 41.5% with water pumps and standard N[O.sub.x] emissions rated at 0.5 or 1.0 g/bhp-hr, Cat said.
The motion analysis includes a force balance on the compressor, which proves essential for determining the mechanical efficiency
based on frictional losses.
* The 16-cylinder G3516E, operating at 50 Hz/1500 rpm and rated 1600 kW and 43.5% mechanical efficiency
without water pumps.
The motor's mechanical efficiency
is said to be very high and provides full torque at startup and throughout the speed range.
Members of the team will be on hand to discuss these technologies, including the Maxima, which has a high mechanical efficiency
, using as little as an unrivalled 5.4kW of electricity to produce a cubic metre of air per minute.
The first is an addition to the company's extensive line of ball ramp brakes that is de signed to provide greater mechanical efficiency
. Typical ball ramp brakes, the company said, provide low mechanical efficiency
with high directional sensitivity, which can result in greater operator effort to engage the brake and less control.
