A DC power supply is formed of an ideal transformer feeding an ideal AC/DC full bridge SCR rectifier. The transformer input is at 120VRMS, and the rectifier nominal output is 24V. The input can fluctuate between 119VRMS and 122.1 VRMS, and the output voltage thus fluctuates between - 0.25% and 0.7% from the nominal voltage, respectively. The load is resistive and can also vary between 20W and 200W where the output voltage for this load range fluctuates between 23.9V and 23.6V, respectively. 1) (8 points) Find the line and load regulation of this power supply.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
