A rotary dryer fired with bunker oil having HHV = 10, 000 kcal/kg is to produce 20 MT/hr of dried sand with 0.5% moisture from wet feed containing 7% moisture. Specific heat of sand is 0.21 BTU/lb-°F. Temperature of wet sand is 30 °C and temperature of dried product is 115 °C. Calculate: a) Weight of wet feed in kg/hr; b) Weight of water removed in kg/hr; c) Heat required in kW; and d) Volume of bunker oil in liters per hr if specific gravity of bunker oil is 0.9 and dryer efficiency is 60%.
