Application: Standing wave ratio and minima and maxima on the line. For a line with characteristic impedance Z0 = 50 Ω and a load R = 220 Ω, calculate:
(a) The standing wave ratio on the line.
(b) If the voltage at the load is 100 V, find the maximum and minimum voltage on the line.
(c) Where do the voltage maxima and minima in occur?
Using the tables for water, determine the specific entropy at the indicated states, in Btu/lb ? 8R In each case, locate the state by hand on a sketch of the T-s diagram.
An air-standard dual cycle has a compression ratio of 9. At the beginning of compression, p1 5 100 kPa, T1 5 300 K, and V1 5 14 L. The heat addition is 22.7 kJ, with one half added at constant volume and one half added at constant pressure. Determi..
