In a mechanical coal-washing process, a portion of the inorganic sulfur and ash material in the mined coal can be removed. A feed stream to the process consists of 73% coal, 11% ash, 11% sulfur, and 5.0% water (to suppress dust). The clean coal side of the process consists of 88% coal, 6.0% sulfur, 3.0% ash, and 3.0% water. The refuse side consists of 32% sulfur, with the remainder being ash, coal, and water. If 80 metric tons per hour of clean coal is required, determine the feed rate required for the mined coal and the composition of the refuse material. Also determine the mass rate for the refuse stream (in metric tons per hour).

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
