A fiberboard sheet (1.5 m × 2.0 m × 15 mm) is being dried by suspending it horizontally in a current of hot, dry air. The edges are insulated so that drying takes place only from the top and bottom surfaces. The wet sheet weighing 16 kg with initial moisture content of 60% loses moisture at a constant rate of 1.25 × 10⁻⁵ kg m⁻² s⁻¹ until the moisture content falls to 30%. All moisture contents are on dry basis. The time required for drying during constant rate period (in hour) is __________ (rounded off to third decimal place).
