1. Calculate densities in lbm/ft3 of the following substances:

(a) a liquid with density of 995 kg/m3. Use (i) conversion factors from the table on the inside front cover and (ii) Equation 3.1-2.

(b) a solid with a specific gravity of 5.7. What did you assume to come up with your answer?

(c) A two-gallon bucket is filled with sand (silicon dioxide, SiO_{2}). The void fraction of the sand (i.e., the empty space between particles, since they don’t pack perfectly tightly) is 0.35*mL of empty space/* *mL of total volume* . If the maximum amount of water is added to the bucket of sand without water spilling over, determine the total mass in the bucket (kg) and specific gravity of the sand-water mixture.

The WorldLight Company produces two light fixtures (products 1 and 2) that require both metal frame parts and electrical components. Management wants to determine how many units of each product to produce per week so as to maximize profit. For each unit of product 1, one unit of frame parts and two units of electrical components are required. For each unit of product 2, three units of frame parts and two units of electrical components are required. The company has a weekly supply of 3,000 units of frame parts and 4,500 units of electrical components. Each unit of product 1 gives a profit of $13, and each unit of product 2, up to 900 units, gives a profit of $26. Any excess over 900 units of product 2 brings no profit, so such an excess has been ruled out.
