Please help me You are to develop a functioning Power Supply that will convert 120Vac from
the wall, and convert it into either a positive 5V or 12V supply or a negative
power supply. The supply will be tested with a .5 Amp load, the supply should
hold steady to the designed voltage level (ie 5V or 12V). There should be no
more than 1% ripple. You have the choice of Half-wave, Full-wave or Bridge
rectifier in your design.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
