Extracted text: Problem 1. (10 points) What is the mass in grams and the weight in dynes and in gram-force of 12 oz of salt? Local g is 31.66 ft/s. Problem 2. (20 points) A spherical tank with a radius of 3 ft is filled with fluid whose density is 650 kgm/m. Determine: a. Total volume of the fluid in ft b. Its mass in slugs and Ibm (Ibm is pound-mass) c. Its specific volume in ft/lbm d. Its specific weight in N/m where g=31.9 ft/s? Problem 3. (10 points) Determine the mass in kgm, and weight in Newton of the air contained in a room whose dimensions are 6m x 6m x 8m. Assume the density of the air is 0.72 lbm/ft and local gravity at 32.1 ft/s?. Problem 4. (10 points) The pressure at the bottom of a certain mountain is 965 mm-Hg and at the same time at the top of the mountain is 845 mm-Hg. Assuming the unit weight of air is equal to 12 N/m2, determine the height of the said mountain. Problem 5. (20 points) In the figure, if the atmospheric pressure is 101. 03 KPa and the pressure at the bottom of the tank is 231.3 KPa, what is the specific gravity of the olive oil? 1.5m SEA OIL - 0.89 2.5m Water 2.9m OUVE.s =? 0.4m MERCURY, s = 116
