A hydraulic press contains 0.25 m³ (250 L) of oil. Find the decrease in the volume of the oil when it is subjected to a pressure increase Ap = 1.6 × 107 Pa (about 160 atm or 2300 psi). The bulk modulus of the oil is B = 5.0 × 10° Pa (about 5.0 × 10* atm), and its compressibility is k = 1/B = 20 × 10¯ atm¯¹.

When a fluid flows in a pipe, the friction between the fluid and the surface of the pipe is given by the coefficient of viscosity n, defined by the equation FIA = n(du/ds), where Fis the force of fric- tion acting across an area A and du/ds is the velocity gradient between layers of fluids. (a) What are the units of n? (b) If AP is the pressure difference and is directly proportional to Al, by using the method of di- mensional analysis, show that AP constant AI
