Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures. There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Three-phase wound-rotor synchronous generators are the main source of electrical power worldwide. They require a prime mover and an exciter in order to generate power. The prime mover can be a turbine spun by fluid (gas or liquid), thus the sources of the fluid can be water running off a dam through a long nozzle, steam from water evaporated using burned coal, etc. Most power plants including coal,...

AC Synchronous Machine Characterization

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Three-phase wound-rotor synchronous motors are less popular than permanent magnet rotor synchronous motors due to the brushes required for the rotor field. Synchronous generators are much more common and available in most existing power plants, as they have excellent frequency and voltage regulation. Synchronous motors have the advantage of almost 0% speed regulation due to the fact that the rotor...

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces. A free-body diagram of the...

Start with the machine’s processing rate and multiply it by the available operating time. The resulting estimate represents potential output before adjustments. Refine it by incorporating cycle time, setup requirements, maintenance, downtime, and efficiency. This mathematical sequence connects a time-based operating schedule with a realistic estimate of how much work the machine can complete.
Cycle time determines how long one processing cycle takes, so shorter cycles generally permit more cycles during the same operating period. Setup time reduces the time available for productive processing because the machine must be prepared before work begins. Including both variables prevents a calculation based only on nominal running time from overstating expected output.
Downtime removes portions of the scheduled period in which no productive work occurs, while efficiency adjusts for the difference between planned and effective performance. Treating the entire period as continuously productive can therefore produce an overly high estimate. Applying these factors gives planners a more realistic basis for comparing available capacity with workload requirements.
Capacity analysis can reveal a bottleneck by showing where available machine output is insufficient relative to the workload that must pass through the process. Comparing capacity estimates across machines helps identify the constrained resource rather than assuming every machine contributes equally. That comparison supports decisions about workload assignment, scheduling, and possible process improvement.
First specify the operating period and defined conditions. Next identify the machine’s processing rate, then account for cycle time, setup, maintenance, downtime, and efficiency. Calculate the resulting capacity and compare it with the expected workload or demand. This workflow creates a consistent mathematical basis for production planning and resource decisions.
Machine Capacity supports scheduling by linking planned workloads to the time and output each machine can provide. A planner can compare available capacity with demand, recognize when resources may be insufficient, and organize work around the machines that can meet requirements. The resulting analysis also helps assess whether existing resources can support the intended production plan.
Capacity figures provide quantitative support for decisions about equipment use, staffing, and process improvement. Comparing calculated capacities can indicate whether resources should be used differently or whether a process requires attention. The same figures also contribute to cost estimation because they connect operating time and processing capability with the amount of work planned.
