Plot Eq. (1-4) as a graph (es vs. T) for a range of temperatures from 30oC to 40°C and a range of pressures from 0 to 70 mb The area below the curve represents the unsaturated air condition. Using this graph, answer the following:
(a) Select two saturated and two unsaturated samples of air from the dataset of pressure and temperature given below:
Pressure (mb): {10, 20, 30}
Temperature (°C): {10, 20, 30}
(b) Let A and B be two air samples, where A: (T = 30°C, P=25 mb) and B: (T = 30°C, P = 30 mb). For each sample, determine the following:
(i) Saturation vapor pressure
(ii) Dew point
(iii) Relative humidity
(c) Suppose both samples A and B were cooled to 15°C. What would be their relative humidity? What would be their dew point temperature?
