Give your answer in kPa, accurate to four significant figures. 25 m3/min of hot air (55°C) with a moisture content of 0.015 kg H20 per kg dry air enters the base of a fluidised bed, which is filled with pelletized cattle feed. The pelletized cattle feed has an initial moisture content of 6.4wt% H2O. At the end of the drying process, which takes 15 minutes to complete and occurs at a constant rate, the cattle feed has 2.8 wt% moisture. Saturated air leaves the fluidised bed at 30°C and 1.06 atm pressure, with 0.0285 kg H20 per kg dry air. A monometer tube connected between the inlet and outlet air streams is filled with a fluid with an SG 2.95. At the beginning of the drying process there is an 80cm difference in the levels of the manometer fluid inside the tube.
