Awet solid is dried in a tray configuration. in one experiment, the total moisture content is reduced from 36% to 8% (dry basis) over a drying time of five hours. the material has an equilibrium moisture content of 5%. the drying rate versus free moisture curve is depicted below, with the critical free moisture content of 10%. how long will it take to reduce the total moisture content of 40% to 7% (dry basis)?

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
