Atensile test is performed on a metal specimen, and it is found that a true plastic strain of 0.16 is produced when a true stress of 575 mpa (83400 psi) is applied; for the same metal, the value of k in the equation is 860 mpa (124700 psi). calculate the true strain that results from the application of a true stress of 600 mpa (87020 psi). enter your answer in accordance to the question statement

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Fluids at rest possess no flow energy. a)- true b)- false

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
