Air at 90°c and 1.00 atm (absolute) contains 10.0 mole% water. a continuous stream of this air enters a compressor–condenser, in which the temperature is lowered to 15.6°c and the pressure is raised to 3.00 atm. the air leaving the condenser is then heated isobarically to 100°c. calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100°c, and the ratio (m3 outlet air at 100°c)/(m3 feed air) at 90°c.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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
