1. Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured in grams per cubic meter (g/m³). Assume that a cumulus cloud occupies a volume of one cubic kilometer, and its liquid water content is 0.2 g/m³. (a) What is the volume of this cloud in cubic miles? (b) How much does the water in the cloud weigh in pounds? 2. A tank of oil has a mass of 3 0 slugs. (a) Determine its weight in pounds and in newtons at the earth's surface. (b) What would be its mass (in slugs) and its weight (in pounds) if located on the moon's surface where the gravitational attraction is approximately one-sixth that at the earth's surface? 3. If p is a pressure, V a velocity, and p a fluid density, what are the dimensions (in the MLT system) of (a) p/p, (b) pvp, and (c) p/pV²? 4. The viscosity of a certain fluid is 5 x 10 poise. Determine its viscosity in both SI and BG units. 5. Crude oil having a viscosity of 9.52 X 10 lb-s/ft2 is contained between parallel plates. The bottom plate is fixed and upper plate moves when a force P is applied (Fig. P1.1). If the distance between the two plates is 0.1 in., what value of P is required to translate the plate with a velocity of 3 ft/s? The effective area of the upper plate is 200 in 2. Ans. 0.476 lb 20 Find plate Figure P1.1: Plate with fixed bottom and upper moving
