What is the elevation of the surface of water reservoir give that velocity in a 1m pipe used to drain the reservoir is v= 10m/s and the pressure in the pipe is p = 200kpa? The elevation of the drain is Z 250m above sea level

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

Write a technical essay (maximum two pages) about stress concentration. and paste from the textbook. instead, read updated material about this phenomenon and provide a technical evaluation of the different techniques to avoid/reduce such phenomenon. consider in your analysis cutting-edge computational techniques such as fea to study and analyze stress concentrations.

Steam enters a converging-diverging nozzle at 1.0 mpa and 500°c with a negligible velocity at a mass flow rate of 2.5 kg/s, and it exits at a pressure of 200 kpa. assuming the flow through the nozzle to be isentropic, determine: the exit area and (a) (b) the exit mach number
