An evaporative cooler is used to cool a space which has a sensible heat load of 15 kW and a latent heat load of 4.8 kW. The dry air mass flow rate of the supply air is 1.4 kg/s. The air leaves the cooler with a db-temperature of 18°C and a relative humidity of 100%. The outdoor air db- temperature is 35°C. The pressure is constant at 101.3 kPa. Determine: (i) the db-temperature and relative humidity of the space, (ii) the outdoor relative humidity, and (iii) the mass flow rate of water.
