1. On a particular day the weather forecast states that the dry bulb temperature is 37$^o$C, while the relative humidity is 50% and the barometric pressure is 101.325 kPa. Find the humidity ratio, dew point temperature and enthalpy of moist air on this day.

Answer:

At 37$^o$C the saturation pressure …

800m³ / min of recalculated air at 22 degrees C DBT and 10 degrees C DPT is to be mixed with 300m³ / mIn of fresh air at 30 degrees C DBT and 50% RH. Determine the enthalpy, specific volume, humidity ratio and dew point temperature of the mixture.
