Please answer in 1hr I have to submit the answer. 1 m of air-water vapor mixture at 36% Relative Humidity, 30 °C and 120 kPa is compressed in a constant temperature process to a state where water just begins to condense. Determine: a) the volume occupied by the mixture when the condensation starts in m², b) pressure at which the mixture becomes completely saturated in kPa, c) the mass of water vapor in the air at the beginning of the condensation process in kg. If the mixture is cooled further to 20 "C, calculate the amount of water that has condensed in kg. Calculate the minimum work input or the maximum work output for the whole process if the surroundings are at 27 °C.
