The Fig P2.1 shows a three-phase, 50 Hz, 15 km long line with 4 ACSR conductors each of diameter and spaced 1.5 m apart in a plane. The power line carries a balanced three-phase rms current of Ia, Ip, and Ic. The fourth wire, which is a neutral, carries zero current. The currents are Ia = -30+j50 A; Ib = -25+j55A; Ic = 55-j105A. (a) Calculate the distances Dan, Don, and Den in meters. [Maximum Points: 2, 2, 2] (b) Find flux linkages pand due to the line currents [Maximum Points: 2, 2, 2] (ii) Determine the total flux linkage in the neutral.

Chapter 06, Practice Problem 4.12: A nozzle is designed to accelerate the fluid from V to V in a linear fashion. That is, V = ax + b, where a and b are constants. When x = 0, V = 26 m/s, and when x = 1, V = 19 m/s. It is also known that aV/2t = 19 m/s and aV/ae = 60 m/s^2. Determine the local acceleration at point 1, the local acceleration at point 2, the convective acceleration at point 1, the convective acceleration at point 2, and the acceleration of the fluid at point 2. V = 10 m/s^2 a_c1 = m/s^2 a_c2 = m/s^2 a_n1 = m/s^2 a_n2 = m/s^2 Please refer to the Work for this question. Open Show Work.
