The magnitude of the line voltage at the terminals of a balanced y-connected load is 660 v. the load impedance is 35.48+j26.86ω/ϕ. the load is fed from a line that has an impedance of 0.25+j3ω/ϕ.a) what is the magnitude of the line current? b) what is the magnitude of the line voltage at the source?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
