Arefrigeration system uses water-cooled condenser for rejecting the waste heat. the system absorbs heat from a space at 25°f at a rate of 24,000 btu/h. water enters the condenser at 65°f at a rate of 1.45 lbm/s. the cop of the system is estimated to be 1.9. determine (a) the power input to the system, in kw,(b) the temperature of the water at the exit of the condenser, in °f and (c) the maximum possible cop of the system. the specific heat of water is 1.0 btu/lbm °f.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
