1. A material with a specific weight of 105 lbf/ft on earth is pressed into a 0.5 ft diameter cylinder and then cut into segments. If each cylindrical segment must be 255 lbm, how long should each segment be? 2. A gate is located at the bottom of a dam on the upstream side. If the water level on this side of the dam is 554 ft, what is the hydrostatic pressure on the gate? If the gate is 1 ft x 4 ft, what is the force on the gate? The gate opens to atmosphere on the other side. 3. An experiment must be conducted at a vacuum pressure of 0.6 atm. What must the absolute pressure be within the experimental chamber? Give your answers in kPa. 4. An approximately 5 ft x 4 ft x 6 ft section of debris weighs 110. lbf. Determine the specific gravity of the section. Will the section float in water? 5. Fuel with a specific gravity of 0.85 is stored in a 25 ft tall cylindrical tank. What is the pressure on the inside walls 12 ft above the bottom when the tank is full? What is the pressure on the floor of the tank when it is half full? The tank is vented to atmosphere. 13 1.
