A vertical cylindrical container is being cooled in ambient air at 25 °C with no air circulation. if the initial temperature of the container surface is 100 °C, compute the surface heat-transfer coefficient due to natural convection during the initial cooling period. the diameter of the container is 1m, and it is 2 m high

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
