In an air conditioning plant, airflow rate of 2 kg/s passes through a coil. The dry-bulb temperature decreases from 25 C to 10 C. The moisture content of the air is 0.005. Determine the load on the coil. Surface temperature of the coil is above the dew-point temperature i.e. the moisture content is constant.
