A sling psychrometer reads 44 °C dry-bulb temperature and 30 °C wet-bulb temperature. Calculate (1) the vapour pressure (bar), (2) the specific humidity, (3) the relative humidity, (4) the dew-point temperature and (5) the enthalpy of the mixture per kg of dry air. Take the barometric pressure as 1.01325 bar; saturation pressures: 0.04242 bar at 30 °C and 0.0910 bar at 44 °C; use steam tables for the dew point.
