HELP ME ASAP PLS Consider: Vapor Pressure at 1500m, in Pa Round to the nearest whole number 8. Estimate the vapor pressure, air pressure, relative humidity, and air density at a height of 1800 m into the atmosphere. The total pressure is 101 kPa, air temperature is 25°C and the dew point temperature is 15°C near the ground, the lapse rate 7.5°C/km, which is constant for both air temperature and dew point temperature. The gas constant R is 287 J/kg-K and constant with respect to altitude.|
Aerodynamic Method
#1 The maximum and minimum temperature recorded at a Lake is 18°C and 15°C in February. The mean air temperature (T), pan evaporation (Ep), wind speed (uz), relative humidity (RH), and net radiation (Rn) in a nearby weather station were found to be 23°C, 15 mm/day, 23 m/s, 47%, 20.54 MJ/m²/day, respectively. Estimate Lake evaporation (mm/day) using: (a) Pan Evaporation method, (b) Aerodynamic method, (c) Energy balance method, and (d) Penman method of combined aerodynamic and energy balance algorithm.
