If the derivative property of phasors is the multiplication of the phasor by jω, the integral property of phasors is division of the phasor by jω. Use phasors and these properties to find the sinusoids in each of the following:
(A) v2 (t) = (1/100) dvi(t)/dt + 20v1(t) and v1(t) = (a) vz(t) = 10 cos(100t + 90°) V
(B) i2(t) = 10 ∫[ i1(t)dt – 3i1(t)] and i1(t) = -4 cos(5t) A

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
