4.71 a full-wave rectifier circuit with a 1-kω operates from a 120-v (rms) 60-hz household supply through a 6-to-1 transformer having a center-tapped secondary winding. it uses two silicon diodes that can be modeled to have a 0.7-v drop for all currents. what is the peak voltage of the rectified output? for what fraction of a cycle does each diode conduct? what is the average output voltage? what is the average current in the load?

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.
