1.If the municipal water rate is one dollar per thousand gallons, how many pounds of water are delivered to the customer's house for one dollar?

2.Rainwater from California is said to contain 0.3 mg/L of silica. What is the silica concentration in the rainwater in ppt, ppb, molarity, and% solution

3.A solid cube with a side length of 0.4 ft and a weight of 110 lb slides down a smooth surface that is inclined at 45 degrees to the horizontal. The block slides on a film of oil with a viscosity of 1.85 x 10-2 lb-s/ft2. If the velocity of the block is 1.2 ft/s, determine the thickness of the oil film assuming a linear velocity distribution in the film.
