An open container contains 1 gallon of hydraulic fluid weighing 7 lbf. The temperature of the hydraulic fluid is increased by 100∘F and the volume of fluid increases to 1.01 gallons. What are the original and final densities of the hydraulic fluid? What is the coefficient of thermal expansion for this fluid?

Calculate the effective coefficient of thermal expansion for a hydraulic fluid with 3% entrained air within a high-pressure hose. The operating temperature is 40∘C.
