A 4-bit A/D converter (0-5V FSR) is used to measure the output voltage from an LVDT. A binary number (1100)2 is returned from the A/D converter. The LVDT has a sensitivity of 0.01V/cm and bias of 0.1V. 1) what is the overall input resolution of the system? 2) what is the possible input displacement to cause this code? 3) what is the overall uncertainty if the converter has nonlinearity error of ±2bits and hysteresis error of ±3bits.

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
