A Carnot heat engine is to be used to produce 250 kW of power using a heat input of 525 kW. For high-temperature reservoirs ranging in temperature between 500 K and 1000 K, plot the corresponding low-temperature reservoir temperatures.
Given: Q?H=525 kW; W?=250 kW
As this is a Carnot (reversible) heat engine, n = nmax = 1 – TC/TH = W/QH = 0.476
For the range of high-temperature reservoir temperatures, the low-temperature reservoir temperatures are

Answer the following statement(s) true (T) or false (F)
1. The work of the modern electrician requires a knowledge of National Electrical Code® requirements that govern three-phase motor installations and the ability to apply these requirements to installations. 2. NEC® Article 430.52 Exception 1 states that if the values for branch-circuit protective devices as determined using the percentages in Table 430.52 do not correspond to the standard device sizes or ratings, then the nearest smaller size rating or setting should be used. 3. When the conductors of a feeder supply two or more motors, the required wire size is determined using Code rules. 4. Wire types and sizes are selected by the ambient temperatures of the place of installation and the economics of the total installation, such as the minimum size of conduits, cost of the wire sizes, and labor cost for installing the various selections. 5. The NEC® guides an electrician through the main components of the calculation, thus providing all the information that is necessary for a motor installation.
