Moist air at standard conditions is at a dry bulb temperature of 80 degree F and a relative humidity of 50%. It is cooled to 50 degree F. Use the psychromtric chart to determine: a- The energy removed from the air after it is cooled in BTU/lb of dry air b- The enerdy removed from the air after it is cooled in BTU/ft^3 c-The amount of moisture removed from the air after it is cooled in lb/lb of dry air d-The amount of moisture removed from the air after it is cooled in lb/ft3 of dry air
