(a) Saturated air at 60°C and a pressure of 105 kPa undergoes a throttling process to a pressure of 80 kPa. Calculate the relative humidity at the final equilibrium state. (b) Saturated air at a pressure of 110 kPa undergoes a constant pressure process from 30°C to 50°C. Calculate the relative humidity in the final state. Assume that air and water vapor behave like ideal gases.
