The rectangular area in Figure 3.26 has a uniform load density of 2000 kVAmile at 0.9 lagging power factor. The nominal voltage of the area being served is 4.16 kV. The threephase primary main conductors are 556,500 267 ACSR, while the threephase lateral conductors are 266,800 267 ACSR. The primary main and the laterals are constructed so that the

A network link (1km long with propagation rate of 2.5 108 msec) utilizes stopandwait (Idle RQ) protocol at the data link layer to transmit frames of 2000 bits. (a) What is the data rate of the link (bitssec) in order to achieve a utilization of 0.8 (10 points) (b) Keeping the frame size constant, should the data rate increase or decrease, and how
