Atmospheric air circulates over a set of cooling coils at 101kPa, 30C and 60% relative humidity, with 1,500 m^3/min being the volumetric flow at the inlet. The condensing liquid is withdrawn from the system at 17C. The final state of the air after further heating is 25C and 60% relative humidity. Determine (a) the heat removed in the cooling zone, in kJ/min, (b) the heat supplied in the heating zone, in kJ/min, and (c) the amount of steam condensed, in kg/min.
