Application of Pascal's Principle: Hydraulics Pascal's principle (also known as Pascal's law) states that when a change in pressure is applied to an enclosed fluid, it is transmitted undiminished to all portions of the fluid and to the walls of its container. F₂ Piston P1-P2 P₁ = P2. F₁ F2 A₁ A₂ = P₂ A 70kg student balances a 1200kg elephant on a hydraulic lift. What is the diameter of the piston the student is standing on? 70 kg Concept: Changes in pressure are transmitted to all parts of the fluid and onto the container. Oil Skill: Using the definition of pressure and Pascal's Principle to calculate. 1200 kg 2.0 m Use density of oil = 900 kg/m^3 Those pistons are circles!

An object hangs from a spring balance.The balance registers 32 N in air, 22 N when this object is immersed in water, and 27 N when the object is immersed in another liquid of unknown density. What is the density of that other liquid? Number i Units V

Water flows from the pipe shown in (Figure 1) with a speed of 4.0 m/s.   Figure 1 of 1   Part A What is the water pressure as it exits into the air?

* Question Co mpi The container shown is filled with a mystery liquid with density 33.5 x103 kg/m³. It is open to atmosphere on the left and closed on the right. What is the pressure at point A, in kPa (kiloPascal)? 1.0 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s². Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. y (cm) 100 % 75- 50 25- f5 0 5 C T f6 < 6 B Y f7 & 4- lip U fg * 4+ K 8 fg KAA 9 f10 ▶11 f11 P 12
