Liquid water flows through a circular pipe with diameter 0.033324 m and length 5 m at a flowrate of 0.369442 kg/s. The pipe is at a constant temperature of 45.7316 °C. The water enters the pipe at a temperature of 20 °C and exits at 37.6988 °C. If the heat transfer coefficient is constant along the length of the pipe, what is its value? (Answer in units of W/m2•K.) (Consider the properties of water as constant corresponding to the average of the inlet and outlet temperature.)

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
