Chapter 1: Properties of Fluids
Supplementary Problems:
1. What would be the weight of one 3 kg mass on a planet where the acceleration due to gravity is 10 m/s²?
2. A vertical cylindrical tank with a diameter of 12 m and a depth of 4 m is filled with water to a top with the water at 20°C. If the water is heated to 50°C, how much water will the spill over? Unit weight of water at 20 degrees celsius and 50 degrees celsius is 9.79 kN/m³ and 9.69 kN/m³.
3. A rigid steel container is partially filled with a liquid at 15 atm. The volume of the liquid is 1.23200 L. At a pressure of 30 atm, the volume of the liquid is 1.23100 L. Find the average bulk modulus of elasticity of the liquid over that given range of pressure if the temperature after compression is allowed to return to its initial value. What is the coefficient of compressibility?
4. Calculate the Density of water vapor at 350kpa abs and 20°C if its gas constant is 0.462 kPa -m³/kg - °K.
5. Air is kept at a pressure of kPa and a temperature of 30°C in a 500-L container. What is the mass of the air?
