Wire electrical-discharge machining (wedm) is a process used to manufacture conductive hard metal components. it uses a continuously moving wire that serves as an electrode. coating on the wire electrode allows for cooling of the wire electrode core and provides an improved cutting performance. an article gave the following sample observations on total coating layer thickness (in µm) of eight wire electrodes used for wedm. 22 17 29 35 43 24 24 25 calculate a 99% ci for the standard deviation of the coating layer thickness distribution. (round your answers to two decimal places.)

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
