The data above was collected with a 35g hanging mass. The Force vs time plot indicates that the average Static Tension is approximately zero Newtons and the Dynamic Tension clearly has an average value that is negative. What is the most probable explanation for the data collection error? HTML EditorKeyboard Shortcuts

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
