A30-kva 8000/230-v distribution transformer has an impedance referred to the primary of 20 + j100 ω. the components of the excitation branch referred to the primary side are rc =100 kω and xm =20 kω (a) if the primary voltage is 7967 v and the load impedance is zl= 2.0 + j0.7 ω. what is the secondary voltage of the transformer? what is the voltage regulation of the transformer? (b) if the load is disconnected and a capacitor of –j3.0 ω is connected in its place, what is

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.

An architect plans to use solar energy to heat the next house he designs. what principle of absorption and infrared energy can be applied to the design of the new house? how could she apply to those principals?
