An eddy current separator is to separate aluminum product from an input streamshredded MSW. The feed rate to the separator is 2,500 kg/hr. The feed is known to contain174 kg of aluminum and 2,326 kg of reject. After operating for 1 hour, a total of 256 kg ofmaterials is collected in the product stream. On close inspection, it is found that 140 kg ofproduct is aluminum. Estimate the % recovery of aluminum product and the % purity of thealuminum produc

Problem 4: Air flows into an open system and carries energy at the rate of 100 kW. When the air leaves the system, the energy rate it carries is 250 KW. In the meantime, the system receives 350 kW power and negligible heat flux. If the system operates in a steady state and no power done by the system, determine the heat loss of the system in unit kW.

You are considering the purchase of a heat pump system with aresistive heating element in the air-handler for back-up during the extra cold winter months when the temperature is below the heat pump's capability. The manufacturer's technical data states the maximum current draw for the unit you are looking at is 18 amps at 240 volts, 1-phase. The circult breaker that you would have to install to carry this resistive load is:

A. 20 amp, 2-pole

B. 40 amp, 1-pole

C. 30 amp, 1-pole

D. 45 amp 2-pole

E. 25 amp. 2-pole
