Question

Part. 1 (2.5 marks): An air mass is at a temperature of 28°C with relative humidity of 70 percent. Determine: (a) Saturation vapor pressure, (b) Saturation deficit, (c) Actual vapor pressure in mbar and mm Hg, (d) Dewpoint Note: 1 mb = 0.75 mmHg


Part. 2 (2.5 marks): Assuming that evaporation for an area is given by E(mm/day) = 0.24(es – e) u Where (es – e) in mb and u in m/s Given that saturation deficit is 7.6 mb and wind speed is 30 km/hr What is the daily evaporation for class A pan (cp = 0.7)?

Answer 1
