Chapter 14, Problem 14.74P

When operating with an open-circuit load and with rated primary voltage, a certain 60-Hz 20kVA 8000/240-V-rms transformer has a primary current of 0.315. A rms and absorbs 360 W. Which of the elements of the equivalent circuit of Figure 14.29(b) on page729 can be determined from this data? Find the numerical values of these elements.

1. (20 pts) Plot the pulse and the FFT for a pulse with the following properties at x=0 and x=10 cm. f=2 MHz m=3 Ncyc=2, 6, 20 po 1 MPa (source pressure) x=10 cm (propagates in a Newtonian fluid for 10 cm as a plane wave-not a sound beam) a=0.5 dB/(MHz cm) Consider 3 types of waves: sine, square, and sawtooth. (square and sawtooth only for grad students) Observe your plots and draw some conclusions. Discuss any possible issues you encounter. 2. (20 pts) We have the following 3 ultrasonic transducers: a. Focused 1 MHz, 2.54 cm diameter, 5.08 cm focus b. Focused 3 MHz, 2.54 cm diameter, 5.08 cm focus c. Unfocused 0.1 MHz, 2.54 cm diameter The transducers are operating in water (c=1486 m/s). I. Plot the axial field for all transducers II. Plot the focal transverse field for the focused transducers and the transverse field at the Rayleigh distance (R_0) and at 2R_0 for the unfocused. III. Assume source pressure of 0.1 MPa, and find the acoustic pressure in MPa at the location (r=0, z=4.5…
