separation process

7) In a single-stage dryer with a dry preheater for fresh air, 380 kg of moist goods must be dried per hour from a moisture ratio of 4.2 to a moisture ratio of 0.95. Incoming drying air maintains a temperature of 10C and a relative humidity of 50%, and a flow of 175 m/min.

What is the lowest temperature to which the drying air must be heated if the drying step can be considered an ideal step and utilized to the maximum (ie exiting air is saturated)? Plot the change in state of the air in a Mollier diagram.

Also calculate the specific air consumption and the specific heat demand for this case.
