You are designing a drier that must evaporate 200 lb/h of h2o from sludge by using air. air at 70°f and 50% relative humidity is drawn into the drier and it leaves at 140f and 70% relative humidity. how much volume of dry air needs to be used for this operation?
b. four hundred kg/h of steam from a low pressure turbine at 12.5 atm. and 250 c goes into a feed water heater which preheats the water entering the economizer in a boiler. the steam is comes out of the feed water at 200 c. the water at a flow rate of 500 kg/h enters the feed water heater at 20c. calculate the feed water exit temperature.

Which step in naming unsaturated hydrocarbons is used for alkenes but not alkynes

What volume would 2.25 moles of ne has occupy at stp?

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
